CELEBRATING 100 YEARS OF
STAINLESS STEEL HISTORY
Today it has been 100 years since stainless steel was
first patented. Harry Brearley was born on Feb 18,
1871 and by 1907 he was managing the Brown-Firth
Research Laboratory in Sheffield, England and he is
given the credit of invention of stainless steel, but there
are many others at the same time shall get credit for
invention of stainless steel such as Pierre Berthier and
Elwood Haynes. Brearley called his new metal "rustless
steel" which is known as Stainless Steel today. French
scientist Leon Gillet had documented the constitution of
stainless steel in 1904. While Gillet noted the
composition and properties of his alloy mix, he never
recognized the corrosive resistance of the material .In
1912, two German's at the Krupp Iron Works, Eduard
Maurer and Benno Strauss, patented the first austenitic
stainless steel of a
21% chromium and 7% nickel combination. Brearley
patented the first martensitic stainless in 1913.
Many inventors have contributed to our knowledge of
why stainless steel is so important and how it resists
corrosion from grades to grades along with its ductility,
Capacity of bearing High temperature and being heat
resistant. Development of steel Started from Cutlery
items such as knife but today its used widely in almost
a l l sec tors f rom cons t ruc t ion, Fabr icat ion,
Pharmaceuticals machineries to railing at our
bungalows or house. Today it has been a century of
stainless steel but the shine of stainless steel
hasn’t yet diminished its shining much
brighter than ever with the increase
in use of Austenitic and Ferritic
grade and of i ts new
members in duplex

long back but the use is gaining in the current
21st century due to its high chromium and
molybdenum content and due to its
advanced resistance to corrosion.
CLASSIFICATION
There are several different
types and grades of stainless
steel. They are classified by
their crystalline structure
AUSTENITIC STAINLESS
STEEL
When nickel is added to
stainless steel in sufficient
amount its crystal structure changes
to "austenite". It has a maximum of 15%
carbon, a minimum of 16% chromium and
sufficient nickel, 6-22, with low carbon. It is strong, easy
to form and weld, and non-magnetic. Popular uses for
austenitic stainless steel are; kitchen sinks, building
facades. Professional food processing equipment,
chemical pipes, and cooking utensils. Austenitic grades
are the most commonly used stainless steels accounting
for more than 70% of production (type 304 is the most
commonly specified grade by far). The most widely
used austenite steel is the 304 grade. The second most
common austenite steel is the 316 grade, used
primarily for its increased resistance to corrosion.
FERRITIC STAINLESS STEEL
The least expensive steel and
has betterengineering
properties than austenitic grades. However, it is
highly corrosive-resistant. It contains
10.5-27% chromium, small amounts of
molybdenum and aluminum or
titanium, and very little nickel. They
are magnetic and cannot be
hardened by heat treatment. A
f e w o f t h e u s e s a r e i n
automobiles, architectural
appl iances, and exhaust
systems.
MARTENSITIC STAINLESS
STEEL
Martensitic steel is produced by
increasing the carbon content of
ferritic stainless steel and heating and
tempering it .These steels are similar to
ferritic steels in being based on Chromium but
have higher Carbon levels up as high as 1%. This allows
them to be hardened and tempered much like carbon
and low-alloy steels and they are magnetic. It is strong
and hard, but brittle and magnetic. They are
used where high strength and moderate
corrosion resistance is required.
Martensitic steel have

ability and formability. It contains
10-17% chromium. It is used for knives,
blades in razors etc.
DUPLEX STAINLESS STEEL
It contains 50% ferritic stainless steel and 50% austenitic
stainless steel and nitrogen is added. Duplex stainless
steels have roughly twice the strength compared to
austenitic stainless steels and also advanced resistance
to corrosion, crevice corrosion and stress corrosion
cracking. They are magnetic but not as much as the
ferritic and martensitic grades. “lean duplex” steels has
comparable corrosion resistance ,enhanced strength
and resistance to stress corrosion cracking. The
“Standard duplex” having 22% chromium content is
widely used duplex grades.“Superduplex” having 25%
chromium content steels have enhanced strength and
resistance to all forms of corrosion. The properties of
duplex stainless steels are achieved with overall lower
alloy content than similar-performing super-austenitic
grades, making their use cost-effective for many
applications. Duplex grades are characterized into
groups based on their alloy content and corrosion
resistance. They are mainly used in hot water heaters
and chemical tankers.
PRECIPITATION HARDENING STAINLESS STEEL
Precipitation hardening stainless steels have corrosion
resistance comparable to austenitic varieties, but can
be precipitation hardened to even higher strengths than
the other martensitic grades. Common grades such as
17-4PH, 17-7PH they have copper added to give it
more strength. These grades are highly used in
Aerospace and defence purpose as well as widely used
for making fasteners.
“UNDERSTANDING THE ROLE OF ALLOYING
ELEMENTS IN MAKING UP OF STAINLESS
STEEL”
NICKEL
The role of nickel is most important in the making of
Stainless steel and it provides the material to resist heat
stabilizes the austenitic structure and increases ductility
and helps the making of stainless steel easier. The
nickel content provides the resistance of corrosion as
well as increases the high temperature strength of the
material and hence it is used in aerospace,
pharmaceuticals as well as chemical and marine
industries. The content of nickel is much more
important while choosing the grades for particular
applications and its industry. It makes the material
non-magnetic in nature. Its content also plays an
important role in resistance of acidic attack when the
material is used in oil industries and it helps particularly
with the attack of sulphuric acid. Nickel is the essential
element in the 300 series stainless steel grades which is
the most used grades in its relevant industries.
CHROMIUM
The higher the chromium level the greater the
protection. It makes a surface film of chromium oxide to
make stainless steel corrosion resistant. It also
increases the scaling resistance at elevated
temperatures. It is a most reactive element and is
responsible for the “passive” nature of all stainless steel
grades. The resistance to the chemical effects of
corrosion and the typical “rusting” (oxidation) that
occurs with unprotected carbon steel is the direct result
of the presence of chromium.
CARBON
Carbon Strengthens stainless steel but promotes the
formation of precipitates harmful to corrosion
resistance. Carbon is always present in stainless steel.
The percentage of carbon content is the important part
in the making of stainless steel. The content of carbon is
very much low except in martensitic as it provides high
strength and hardness.
Metalmentalist - June 201210
Cover StoryCover StoryCover Story
COPPER
Copper is added to stainless steels to increase their
resistance to certain corrosive environments. Copper is
known to decrease the metallic dissolution rate in acidic
media and consequently to slower the propagation pit
growth rate. I t also decreases susceptibil i ty
to s t ress corros ion crack ing and prov ides
age-hardening effects.
MOLYBDENUM
The more higher the molybdenum content, the better
the resistance to higher chloride levels. Molybdenum
Increases corrosion resistance, strength at elevated
temperatures, and creep resistance. It expands the
range of passivity and counteracts tendency to pit
especially in chloride environments. The addition of
molybdenum to the Cr-Fe-Ni mixture makes it
resistance to localized pitting attack and better
resistance. It helps resist the detrimental effects of
chlorides.
MANGANESE
Promotes the stability of austenite, at or near room
temperature and improves hot working properties.
Addition of up to 2% manganese has no effect on
strength, ductility and toughness. Manganese is
important as a partial replacement of nickel in 200
series stainless grades. Generally manganese is added
to stainless steels to assist in de-oxidation, during
melting, and to prevent the formation of iron sulphide
inclusions which can cause hot cracking problems. It is
also a “austenite” stabilizer and when added in higher
levels (from 4 to 15%) replaces some of the nickel in the
200 series stainless steel grades.
TITANIUM
Titanium is the main element used to stabilize stainless
steel. When stainless steel is melted in air, it is difficult to
reducing the carbon levels. Titanium will react with the
carbon to form titanium carbides and prevent the
formation of chrome carbides, which could affect the
formation of the “passive” layer. The most common
grade today is 304 (with 0.08 max carbon, although in
reality the levels are lower).
SILICON
Silicon resists carburizing at high temperatures and
slightly increases tensile strength and hardness. Silicon
Increases scaling resistance by forming a tight initial
scale, which will withstand cyclic temperature changes.
Small amounts of silicon are added to all grades of
stainless for deoxidizing. Small amounts of silicon and
copper are usually added to the austenitic stainless
steels containing molybdenum to improve corrosion
resistance to sulphuric acid. Silicon also improves
oxidation resistance and is a “ferrite” stabilizer. In
“austenitic stainless steels, high silicon contents
improves resistance to oxidation and also prevents
carburizing at elevated temperatures (309 and 310 are
examples).
“STAINLESS STEEL STILL REMAINS STRONG
AFTER 100 YEARS AS ITS USAGE GOES ON
AND ON…!!”
Significant future growth is foreseen in the use of
stainless steel. Stainless steel is a versatile material. First
used for cutlery and from domestic use it went to

architectural, engineering, aerospace, marine,
chemical, oil and gas industry because of its corrosion
resistant characteristics. Corrosion resistance is of great
importance and slowly but steadily the mechanical
characteristics of the material are being recognized. It is
a material that keeps on finding its way into new
applications on a close to daily bases. Below you
w i l l f ind a number o f
applications where stainless
s tee l has proven i t se l f
through many years of
reliable service.
DOMESTIC USE
The invention of stainless
s t e e l s t a r t e d f r o m
manufacture of cutlery items
such as knifes. The finest
cutlery uses are specially
produced from stainless steel
410 and 420 for the knives,
razor blades and grade 304
for the spoons and forks,
cutlery, sinks, stands the most
well known application stainless steels is probably for
cutlery, kitchenware as well as for our daily materials in
domestic use.
ARCHITECTURAL/CIVIL ENGINEERING
Stainless steel usage for cladding, handrails, door and
window fittings, street furniture, structural sections,
reinforcement bar, lighting columns, lintels, masonry
supports are growing day by day as many modern
buildings use stainless steels for cladding, roofing and
facades as it has a good life and remains rust free for
many years. I ts low maintenance cost and
anti-corrosive characteristics of stainless provides a
growing market in public transport, ticket machines
and street furniture. Stainless steel reinforcing bar,
although initially expensive, is proving to have very
good life cycle costing characteristics.
TRANSPORT
The market for stainless steel continues to improve by
manufacturing exhaust systems, car trim/grilles, road
tankers, ship containers, ships chemical tankers With
greater concentration being made to achieving Green
Revolution, low long term maintenance costs, less
environmental impact and greater concern with life
cycle costs,. Cars are making increasing use of stainless
steel, primarily for exhaust systems and catalytic
converters, but also for structural purpose as it
increases its strength as well as Protects from damages
cause due to accidents.
CHEMICAL/PHARMACEUTICAL, OIL AND GAS
Probably the most demanding industries that use
stainless steels are the chemical, processing and oil &
gas industries have created a large market for stainless
tanks, pipes, pumps and valves as well. One of the first
major success stories on stainless steel 304 was the
storage of dilute nitric acid as it could be used in thinner
sections and was more robust than other materials.
Special grades of stainless have been developed to
have greater corrosion resistance at a broad range of
different temperatures.
MEDICAL – SURGICAL INSTRUMENTS,
SURGICAL IMPLANTS, MRI SCANNERS.
Especially clean melted stainless is used for medical
implants and artificial hips. A great deal of medical
equipment - such as orthopedic beds, cabinets and
examination machines - is made as standard from
stainless because of its hygienic and easy-clean
qualities. Pharmaceutical companies use stainless for
pill funnels and hoppers and for piping creams and
solutions.

RUPEE WEAKNESS AFFECTS
STEEL PRICES IN INDIA
At a time when global
industrial activity is slowing
down, the demand for the
steel in the sectors of
infrastructure, construction
a n d a u t o m o b i l e i s
uncertain and the major
f a c t o r o f R u p e e
depreciation is detrimental
for businesses of import of
steel raw material or
f i n i s h e d g o o d s f o r
manufacturing purposes.
With manufacturing of
steel products being the core of our business, the
necessity of importing the raw material is high. The
Indian Rupee has depreciated more than 5 percent on a
year-to-date basis and considering the current state of
the global economy, weakness in the Rupee could
continue due to global economic and euro zone crisis.
From the industry point of view, depreciation in the Rupee
has led to rise in import costs for the steel manufacturing
companies in India. Iron ore and coal being major inputs
in steel manufacturing have seen a softening of prices on
the international front, but in the Indian markets the
scenario is different.
Once the global economic scenario stabilizes, we could
possibly see a reversal in the currency and this would
bring a relief to the Indian markets. But a factor still
remains crucial to the industrial metals space as the
economic scenario in China and in Europe the weak
economy has lead to weak demand of steels.
Considering the expected slowdown in Chinese
economic activity and the eurozone crisis, we feel that,
Indian markets too would feel a pinch of the same.

DECLINING NICKEL COSTS
FAIL TO STIMULATE
STAINLESS STEEL MARKET
Stainless steel markets throughout the world are in a
subdued mood, reflecting a general, global malaise.
Transaction values are down in most countries. This has
combined with seasonal buying patterns and caution
arising from the economic situation to bring about
severely depressed business activity in many markets.
Most countries in Europe have reported very low
purchase volumes in recent weeks. Basis values are close
to breakeven levels and the LME nickel price has recently
recorded its lowest figures since 2009. Buyers are
understandably cautious, given the overall economic
climate. The ongoing uncertainty over Greece's
continued participation in the euro has led politicians
and business leaders to consider the consequences of the
country's hypothetical exit from the single currency and
possible default. This could cause a knock-on effect on
the other weakest members of the euro zone - Italy,
Spain, Portugal and Ireland - and more wide reaching
consequences for banks, businesses and governments
throughout the region who trade with these nations.
The situation in Scandinavia is slightly more
encouraging. Financial systems there are less exposed to
the turmoil in the south of Europe. Furthermore, there is
significant investment in Norway's North Sea oil interests,
while Sweden's manufacturers of trucks and yellow
goods, for example, and maintain strong export volumes
to developing nations, such as Brazil.
The recovery in industrial activity in the United States,
since the global financial crisis, has been quicker and
stronger than in Europe. However, markets there, too are
becalmed at present. The optimism usually associated
with an impending presidential election is not apparent
on this occasion. Moreover, given the global surfeit of
production, domestic suppliers are subject to
competition from imports from Asia, particularly on the
west coast and, to some extent, from Europe, in the east.
Whilst growth in consumption and output continues in
China, the rate of that expansion has certainly slowed in
the past twelve months. The huge investment in new

Pressure Vessels
A pressure vessel is defined as “a vessel in which the pressure is obtained from an indirect source or by the application of heat
from an indirect source or a direct source. The vessel proper terminates at: (a) the first circumferential joint for welded end
connections; (b) the face of the first flange in bolted flange connections; or (c) the first threaded joint in threaded connections."
Pressure vessels include but are not limited to compressed gas storage tanks (i.e., air, oxygen, nitrogen tanks, etc.), anhydrous
ammonia tanks, hydro pneumatic tanks, autoclaves, hot water storage tanks, chemical reactors and refrigerant vessels,
designed for a pressure greater than 15 psi and a volume greater than 5 cubic feet in volume or one and one-half cubic feet in
volume with a pressure greater than 600 psi.
Heat ExchangersA heat exchanger is a specialized device that assists in
the transfer of heat from one fluid to the other. In some
cases, a solid wall may separate the fluids and prevent
them from mixing. In other designs, the fluids may be in
direct contact with each other. In the most efficient heat
exchangers, the surface area of the wall between the
fluids is maximized while simultaneously minimizing the
fluid flow resistance. Fins or corrugations are
sometimes used with the wall in order to increase the
surface area and to induce turbulence.
Spray dryersSpray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas. This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals. A consistent particle size distribution is a reason for spray drying some industrial products such as catalysts. Air is the heated drying media; however, if the liquid is a flammable solvent such as ethanol or the product is oxygen-sensitive then nitrogen is used.
All spray dryers use some type of atomizer or spray nozzle to disperse the liquid or slurry into a controlled drop size spray. The most common of these are rotary disks and single-fluid high pressure swirl nozzles. Alternatively, for some applications two-fluid or ultrasonic nozzles are used. Depending on the process needs, drop sizes from 10 to 500 µm can be achieved with the appropriate choices. The most common applications are in the 100 to 200 µm diameter range.
ExtractorsExtractors are data retrieval mechanisms in the SAP source system. This can fill the extract structure of a data source with the data from the SAP source system datasets. The extractor may be able to supply data to more fields than exist in the extract structure.
DeodorizerA deodorizer is an equipment for deodorizing, the final stage in vegetable oil refining. Deodorizing removes odoriferous material, free fatty acids and other undesired minor components to produce bland oil with a good shelf life.

plant in recent years has brought about substantial overcapacity in the Far East,
especially at current levels of demand. Now, all the major stainless steel
producing nations in the region are trying to export their excess output to each
other. There is now the prospect of Taiwanese producers attempting to bring
antidumping actions against Chinese and South Korean suppliers.
One ray of light is that the Chinese government is believed to be implementing a
new stimulus package, worth around 2 trillion Yuan ($Us316 billion), aimed at
counteracting the downturn in growth. Funding will be available for investment in
infrastructure schemes, such as railways, environmental projects and social
housing. The financial injection will be around half the size of the previous
spending boost unveiled in 2008. On this occasion, the state hopes to encourage
greater private-sector involvement.
GLOBAL STEEL MARKET ROUND UP
FROM MEPS
In the US, both strip and plate prices are being negatively influenced by imports.
Climbing domestic output and short delivery lead times are exacerbating the
situation. However, lower scrap prices have eased some of the cost pressures on
the steelmakers.
In Canada, mill activity held steady throughout May, with steelmakers reporting
good order intake, although some distributors noted that delivery lead times are
relatively short. Selling values have softened a little. Demand is reasonable but

not strong. However, raw material costs are still high enough to encourage producers to lift transaction figures
whenever possible.
Chinese market prices have been declined in May. Although Baosteel elected to keep June’s official ex-works figures
flat, several other producers have reduced theirs. This has not helped market sentiment which was already weak.
Domestic demand is rebuilding in Japan, while export volumes are also growing, due to the weaker yen. Sales to the
auto and construction industries are forecast to stay firm. Major producers of strip mill products are planning a rise of
around ¥5000 per tonne. The negotiations with customers are ongoing. The hikes are cost driven and also reflect
recent increases in the price of imported steel.
South Korean mills continue to struggle to implement any advances as buyers resist their initiatives. Domestic demand
from construction and shipbuilding is weak, although the auto sector is performing relatively well. Total inventories of
flat products, held by distributors, at end March, rose by around 3 percent, compared with April.
The appreciating Taiwanese dollar is helping that country’s steelmakers to reduce their raw material costs, whilst, at
the same time, encouraging cheap imports. Overall sales remain sluggish, although some downstream industries
have been doing slightly better lately.

NICKEL AND NICKEL ALLOYSHISTORY
Nickel is the most versatile Element of all. Nickel is a naturally
occurring, lustrous, silvery-white metallic element. It is the
fifth most common element on earth and occurs extensively
in the earth's crust. Nickel has been used in alloys long back
to the dawn of civilization more than 2000 to 3000 Years
ago. It was first identified and isolated as an element by the
Swedish chemist, Axel Cronstedt, in 1751. It name comes
from the Saxon term 'Kupfernickel' as the 15th century
miners thought the ore looked Reddish brown like
copper but it was too difficult to mine. Nickel in
elemental form or alloyed with other metals and
materials has made significant contributions to our
present-day society and promises to continue to
supply materials for an even more demanding
future. Complete solid solubility exists between nickel
and copper. Wide solubility ranges between iron,
chromium, and nickel make possible many alloy combinations. Stainless steels which was discovered
early in the 20th century and nickel content had a very important role in the invention of the same,
and still 61% of the nickel is used in manufacturing Nickel alloys balance for making other nickel high
temperature alloys and plating. When nickel is added to other element its Alloys were found to have
excellent corrosion resistance and high temperature resistance, which made them suitable for
Aerospace, Chemical, Pharmaceuticals Industry, Heat exchangers and energy. Still the metal is known
to be the future Metal as its value and usage is increasing in 20th century. Nickel has its presence in
over 3lakh products for consumer, industrial, military, transport, aerospace, marine and
architectural applications. The biggest use is in alloying with chromium and other metals to
produce stainless and heat-resisting steels.
OVERVIEW
60% of Nickel Is mostly used for making Stainless steels, 14% in copper nickel alloys such as
alloy 400 and alloy 500, 6% to make superalloys such as alloy 625, 800, 718 Etc. 9% in plating, 5%
in heat and electric resistance alloys, such as Nichrome, 6% for in all other applications combined.
Nickel foam or nickel mesh is used in gas diffusion electrodes for alkaline fuel cells. Nickel is
used in many specific and recognizable industrial and consumer products, including stainless
steel, coins, rechargeable batteries, electric guitar strings, microphone capsules, and
special alloys.

Nickel is widely used as an alloy metal, and its main use is in the nickel manufacturing stainless steel, duplex steel and
other high temperature and heat resistant alloys. It is also widely used in many other alloys, such as nickel brasses and
bronzes, and alloys with copper, chromium, aluminium, lead, cobalt, silver, and gold. Because of its resistance to
corrosion, nickel has been occasionally used historically as a substitute for decorative silver. Nickel is used as a binder
in the cemented tungsten carbide or hard metal industry and used in proportions of 6 to 12% by weight. Nickel can
make the tungsten carbide magnetic and adds corrosion-resistant properties to the cemented tungsten carbide parts,
although the hardness is lower than those of parts made with cobalt binder.
WHERE & WHY NICKEL IS USED
Nickel-containing materials play a major role in our everyday lives – food preparation
equipment, mobile phones, medical equipment, transport, buildings, power generation – the
list is almost endless. They are selected because - compared
with other materials - they offer better corrosion
resistance, better toughness, better strength at high
and low temperatures, and a range of special
magnetic and electronic properties. Most
important are alloys of iron, nickel and
chromium, of which stainless steels
(frequently 8-12% nickel) are the largest
volume. Nickel based alloys - like stainless
steel but with higher nickel contents - are used for
more demanding applications such as gas turbines and
some chemical plants.
In addition, iron and nickel alloys are used in electronics and specialist engineering, while copper-nickel
alloys are used for coinage and marine engineering. There are about 3000 nickel-containing alloys in
everyday use. About 90% of all new nickel sold each year goes into alloys, two-thirds going into stainless
steel. Nickel metal is used to provide hard-wearing decorative and engineering coatings as 'nickel-plating'
or 'electroless nickel coating' or 'electroforming'. When used with a top layer of chromium, it is popularly
known as 'chrome-plating'. When done in combination with silicon carbide it is known as composite
plating.
Nickel is a key part of several rechargeable battery systems used in electronics, power tools,
transport and emergency power supply. Most important today are nickel-metal hydride (NiMH).
Nickel is a key ingredient in many catalysts used to make chemical reactions more efficient. Nickel
use is growing at about 4% each year while use of nickel-containing stainless steel is growing at about 6%.
The fastest growth today is seen in the newly and rapidly industrializing countries, especially in Asia.
Nickel-containing materials are needed to modernize infrastructure, for industry and to meet the material
aspirations of their populations.
A list of some of the major nickel alloy and nickel stainless steel producers in the world is

available here. Most nickel-containing products have long useful lives.
Average life is probably 25-35 years, with many applications lasting
much longer. Nickel containing products frequently can provide
optimum solutions to practical challenges at a lower total cost and with
more efficient use of resources, including energy.
At the end of their useful life, nickel-containing products can be
collected and recycled for future use and re-use. Nickel is one of the
most recycled materials globally. It is collected and recycled, mostly in
the form of alloys. About half of the nickel content of a stainless steel
product today will have come from recycled sources. For more
information on nickel recycling go to Recycling. Nickel is of
considerable economic and strategic importance to many countries, as
can be appreciated from the wide diversity of end-use industries which
it serves. It is traded on the London Metal Exchange.
The International Nickel Study Group, based in The Hague,
Netherlands, is an inter-governmental body which publishes monthly
statistics on nickel supply and demand, and acts as a forum for the
exchange of information and views on nickel trends. Nickel and nickel
compounds can in certain circumstances be associated with toxicity,
carcinogenicity and with dermal sensitization. Most of the practical
risks associated with nickel hazards are seen in certain complex
processes used in nickel production and refining. The risks are well
known and are managed and controlled by specific workplace
regulation.
In the nickel industry's view, significant risks are not normally associated
with the use of nickel, nickel-containing alloys or nickel-containing
products, with the exception of the use of nickel and some nickel alloys
in jewellery. Nickel use makes a very high practical contribution to
improvements of health, safety and protection of the environment.
Society will lose a lot more than it will gain if it adopts an excessively
precautionary approach to the assessment and management of the
risks associated with nickel.

NICKEL INSTITUTE CELEBRATES
STAINLESS STEEL CENTENARY IN
BEIJING
As part of the Centenary of Stainless Steel
celebrations, the Nickel Institute today hosted an event
in Beijing ‘Nickel and Stainless Steel – Towards the Next
100 Years’. This event showed representatives from the
metals industries as well as policymakers and
researchers how nickel and the Nickel Institute are key
partners in the success of stainless steel.
Stainless steel was one of the major discoveries of the
20th Century. Contributing to our safety and quality of
life, stainless steel is an integral element of our daily
lives. Not only is nickel a crucial ingredient in stainless
steel but the Nickel Institute has worked for decades to
promote stainless steel and develop the markets for its
wide-ranging applications. The Nickel Institute
provides end-users with information and training to
enable them to fully understand the benefits stainless
steel can bring to applications like food, beverage and
drinking water production, architecture, transport,
chemical and energy production and healthcare.
In China where the ‘Nickel and Stainless Steel - Towards
the Next 100 Years’ event was held, demand for
stainless steel is still growing. Part of the Nickel
Institute’s role is to work with its partners across the
value chain to demonstrate the sustainability and
recyclability of stainless steel. Our aim is to inform both
industry and pol icymakers, to improve the
understanding of the sustainability profile of stainless
steel and to reverse policy trends towards regulation
based solely on hazard.
Dr Kevin Bradley, Nickel Institute President said,
“Despite a solid 100-year history, stainless steel is
very much a material for the future. We are
working tirelessly with our partners to highlight
stainless steels contribution to society and to
sustainability. By working together across
the value chain, we are committed to
addressing any barriers which could
prevent stainless steel from achieving
its full potential in the next hundred
years.

ALUMINIUM AND
A L U M I N I U M
ALLOYSINTRODUCTION
Aluminium is found primarily in bauxite ore. Pure
aluminium is soft, silvery , ductile of the poor metal
group of chemical elements ,which is corrosion
resistant, light weight and high electrical conductivity.
The metal obtained its name from the Latin word form
alum, alumen. The name alumina was provided by
L. B. G. de Moreveau, in 1761 for the base in alum,
which was positively shown in 1787 to be the oxide the
undiscovered metal. In 1807, Sir Humphrey Davy said
that the undiscovered metal shall be referred to as
aluminum. This was then altered further to that of
aluminium so to agree with the "ium" spelling that
ended most of the elements. The metal is used in many
industries to manufacture a large variety of products
and is very important to the world economy. Aluminium
alloys are most important alloys which are use in the
important sectors of the world such as aerospace due to
its high strength-to-weight ratio. The most common
aluminium alloying elements are copper, magnesium,
manganese, silicon and zinc.
OVERVIEW
There are two principal classifications, namely casting
alloys and wrought alloys. About 85% of aluminium is
used for wrought products, for example rolled plate,
foils and extrusions. Cast aluminium alloys yield cost
effective products due to the low melting point. The
most important cast aluminium alloy is Al-Si, where the
high levels of silicon (4.0% to 13%) contribute to give
good casting characteristics. Aluminium alloys are
widely used in engineering structures and components
where corrosion resistance is required. On the opposite
hand, pure aluminium metal is far too soft for such
uses, and it doesn't have the high tensile strength that's
required for airplanes and helicopters.
Aluminium alloys with a good composition of
properties are utilized in engineering structures. Alloys
composed mostly of the two lightweight metals
aluminium and magnesium have been very important
i n a e r o s p a c e
manufacturing.
Metalmentalist - June 201224
Aluminium alloy surfaces will keep their
apparent shine in a dry environment due to
the formation of a clear, protective layer of
aluminium oxide. Aluminium alloys with a
wide range of properties are used in
engineering structures. Selecting the right
alloy for a given application entails
considerations of its tensile strength,
dens i t y, duc t i l i t y, f o rmab i l i t y,
workability, weldability, and corrosion
resistance, to name a few. Structural
components made from aluminium
and its alloys are vital to the aerospace
industry and very important in other
areas of transportation and building. It is
widely used for foil and conductor cables, but
alloying with other elements is necessary to provide the
higher strengths needed for other applications.
Aluminium alloys in comparison to steel and its alloys
With the change in new metal products, the design
choices are of ten known by the choice of
manufacturing techniques. Extrusions are particularly
important in the current century as owing to the ease
with which aluminium alloys, particularly the
aluminum, magnesium and silicon alloy series, can be
extruded to form complex extrusions. Aluminium alloys
have an elastic modulus of about 70 GPa, which is
about 1/3rd of the elastic modulus of
many kinds of steel and its alloys.
Hence component made
up of an aluminum
alloy will
experience a greater elastic deformation than a same
part of steel which is identical in size and shape. Though
there are aluminium alloys with somewhat-higher
tensile strengths than the commonly used kinds of steel,
but selecting the right alloy of aluminium or steel for the
respective component is also the factor as just replacing
some alloys won’t help the component.
With aluminium alloys, stiffer and lighter designs can
be achieved rather than steels. Aluminium alloys are
hence mainly used in parts that require high tensile
strength. In automotive engineering, cars made of
aluminium alloys uses space frames made of extruded
profiles to ensure rigidity. Aluminum alloys do not have
this lower fatigue limit and will continue to weaken with
continued stress cycles. Aluminium alloys are majorly
used in automotive engines, due to the weight
savings that are possible. Since aluminium alloys
can resist high temperatures, the cooling
sys tem of such engines is cr i t ical .
M a n u f a c t u r i n g t e c h n i q u e s a n d
metallurgical advancements have also
been important for the successful

Aluminium AlloysAluminium AlloysAluminium Alloys
application in automotive engines. An important
structural limitation of aluminium alloys is their lower
fatigue strength compared to steel.
TYPES OF ALUMINIUM ALLOYS
There are two types of alloys Wrought and cast
aluminum alloys. Wrought aluminum is known with a
four digit number which identifies the alloying
elements. Cast aluminum alloys use a four to five digit
number with a decimal point. The digit in the hundreds
place indicates the alloying elements, while the digit
after the decimal point indicates the form (cast shape
or ingot).
WROUGHT ALLOYS
1000 SERIES 1000 series are commonly known as commercially
pure aluminium grade with a minimum 99% aluminum
content by weight. 1000 series aluminium having
higher purity is used in many applications especially in
the electrical and chemical fields due to corrosion
resistance, high thermal and electrical conductivity, low
mechanical properties, and excellent workability. Iron
and silicon are the major impurities.
2000 SERIES Copper is the principal alloying element in this group.
2000 series are aluminium alloy which consist of
copper ranging from 2% to 5% which can be hardened
to strengths comparable to steel. There are most
common aerospace alloys for its high tensile strengths.
In some instances artificial ageing is employed to
further increase the mechanical properties. These
alloys are processed to solution heat-treatment to
properties at its highest level and in the heat-treated
condition mechanical properties are similar to and
sometimes exceed those of some alloy steel.
3000 SERIES These aluminium alloys are alloyed with manganese.
These alloys are popular and widely used as
general-purpose alloys for moderate-strength
applications requiring good workability. Manganese
is the major alloying element of alloys in this group,
which is not heat treatable as only a limited percentage
of manganese, up to about 1.5%, can only be added to
aluminium, it is used as a major element in only a few
instances.
4000 SERIESThese alloys are also known as silumin as are alloyed
with silicon which can be added in sufficient quantities
Metalmentalist - June 201226
Aluminium AlloysAluminium AlloysAluminium Alloys
to cause substantial lowering of the melting point
without producing brittleness in the formation of alloys.
These alloys are non heat treatable but due to alloying
elements it responds well to the heat treatment to an
extent. Hence aluminium-silicon alloys are used in
welding wire and as brazing alloys where lower melting
point is required.
5000 SERIES Magnesium is one of the most effective and widely used
alloying elements for aluminium. Magnesium is
considerably much effective than manganese as it is
stronger and harder, about 0.8% magnesium being
equal to 1.25% manganese, and it can be added in
considerably higher quantities. These alloys are also
known as marine grade alloys (5083,5086) as they are
widely used in marine applications. When it is used as
the major alloying element, or with manganese, the
result is a moderate to high- strength non-heat
treatable alloy Alloys in this series possess good
welding characteristics and good resistance to
corrosion in marine atmospheres.
6000 SERIESThese alloys are not as strong as the 2000 series alloys
or 5000 series alloys as they are alloyed with
magnesium and silicon which are easy in machining.
Alloys in this group contain silicon and magnesium in
approximate proportions thus making them capable of
being heat-treated. As compared to other strong alloys,
with average strength these alloys possess good
formability and corrosion resistance.
7000 SERIES The strongest of all the alloys in Aluminium, They are
known as aerospace alloys. This alloy is the most
important alloy in current aerospace industry. Zinc
being the major alloying element in this group, and
added with a smaller percentage of the magnesium
results in heat-treatable alloys of very high strength.
Usually other elements such as coppers and chromium
are also added in small quantities. They are alloyed
with zinc, and can be precipitation hardened to the
highest strengths of any aluminum alloy.

Nickel“From the month of February’12 onwards, nickel is witnessing a downtrend in prices as weak global economic prospects along wi th expectations of a surplus in 2012 and 2013.” From an average of around $19,940/tonne in January’12, nickel prices on the LME have slipped to an average of $17,000/tonne in May’12. In the Indian markets, prices on the MCX have declined from a monthly average of Rs1016/kg in January12 to Rs.940/kg in May’12. When the price performance of the metal is compared from Janueary’12 to May’12, then it shows that in dollar terms prices corrected 15 percent, while in Rupee terms the metal prices fell only 7 percent due to the factor of Rupee depreciation which cushioned sharp downside in prices. In the current scenario, demand concerns for the metal have increased as China, which accounts for a whopping 46 percent share in world nickel consumption is expected to witness a slowdown in economic growth. Other major nickel consumer such as the US and the Euro Zone are also expected to witness slow growth in demand due to the ongoing economic concerns. On the inventories front, commercial nickel stocks at the end of the last year stood at 96,848 tonnes. But despite a fall in nickel inventory levels last year, the metal prices slipped due to heightening macroeconomic worries. As far as demand-supply is concerned, a deficit was seen in the global nickel market in 2010 and 2011. The deficit seen in the last year was mainly due to a sharp increase in nickel consumption in the last few months of 2011 by China. But inventories in the current year are expected to witness an increase as
production is forecast to exceed consumption in 2012. Downside in nickel prices is expected to continue in the short-term on account of the expected rise in inventories, concerns on the macroeconomic front along with expectations of a surplus. From a one month’s perspective, we recommend a Sell in the MCX Nickel June contract around 950 with a Stop Loss of 980 and a Target of 870.

ALUMINUM Aluminum slipped below the crucial $2000/tonne mark on the LME as heightening global economic concerns along with strength in the US Dollar Index added to
pressure on prices. However, “further decline in aluminum prices could be restricted as cues remain negative, considering the current macroeconomic scenario.” World aluminum
consumption grew at a pace of 5.9 percent in 2011 and EIU expects growth to slow down at 4.8 percent for 2012. This is because ongoing global European economic worries will have an impact on investment and business confidence in the Euro Zone. But global demand is not expected to witness sharp deceleration on account of consumption which will be supported by the recovery in supply chains in the auto sector after the disruptions that were caused in the March’11 earthquake in Japan.
China’s Aluminum consumption is expected to witness slow growth at around 6 percent for 2012 and 2013, compared to previous 11.5 percent in 2011 and 10.5 percent in 2010. The weak economic scenario in China is
expected t o r e s t r i c t
growth in manufactured products, thus leading to lower
demand. The rail i n f r a s t r u c t u r e p r o j e c t o f high-speed in China has been scaled down, and earlier growth expectations were made keeping in mind the huge demand that would come from this segment. On the overall demand front, demand from Japan is expected to improve post the earthquake and tsunami. Demand in Japan is expected to grow in the auto sector on account of as Japanese carmakers receive tax breaks and subsidies. US demand is expected to improve after witnessing a decline in consumption by more than 4 percent in last year. This year, aluminum consumption in the US could rise more than 3 percent according to the WBMS as the auto sector is indicating better performance than 2011. The Indian economy in the current year is going through a slow growth phase and demand growth is expected to fall from more than 9 percent year-on-year in 2011 to around 6 percent in the 2012 as car manufacturing witnesses a slow growth phase. On the supply front, world aluminum production is expected to grow at a slow rate of 4.6 percent in 2012, which is down from 6.4 percent in last year. Due to rising energy costs, the usage of secondary aluminum is expected to rise. In the Euro Zone, concerns on the environmental front will affect production and China too will face a decline in production due to restrictions on electricity usage and higher energy costs. Nevertheless, the aluminum price scenario would be more dependent on global happenings than on actual demand-supply fundamentals. Taking cues from sentiments and developments on the macroeconomic front Aluminum is expected to trade on a negative note with less clarity over the re-emergence of Euro Zone from its worst debt crisis, thus leading to a pressure on aluminum prices in the short-term. From a one month’s perspective, we recommend a Sell in MCX Aluminum June contract around 111 – 111.50 with a Stop Loss of 114 and a Target of 105 (CMP: 109).

COPPERIn the current context, a major factor that is driving the global financial markets is the developments on the macroeconomic front, which in our opinion are not supportive for positive risk sentiments. While on one hand expectations with respect to actions by global policymakers is on the rise, on the other hand, investors remain cautious considering the uncertainty surrounding the European debt crisis. Base metals are used for industrial purposes and slowdown in economic growth affects price performance. On the London Metal Exchange (LME), Copper prices are currently trading below $7300/tonne as the ongoing global economic worries are having a negative impact on prices. At the beginning of May’12, copper prices on the LME were trading around $8430/tonnes, but downtrend in prices continued thereafter as worries over demand prospects emerged due to the slowdown in economic growth in major economies. Apart from this, strength in the US Dollar Index (DX) and low risk appetite among investors also affected prices. A major factor that helped cushion sharp downside in prices was the decline in LME inventories by 4.4 percent in the month of May’12.
In case of the red metal, fundamentals look bearish from the short-term perspective as slow Chinese economic growth will lead to lower demand for the metal. Chinese copper demand is expected grow at a slow pace of 6 percent in 2012 from 6.7 percent in 2011 as per the Economic Intelligence Unit (EIU). In spite of slow economic growth and expectations of decline in demand for the year, Chinese imports have increased sharply at the end of 2011 and in the beginning of 2012. Chinese copper imports stood around 711, 311 tonnes, for January’12 and February’12, marking a rise of 75 percent on a year-on-year basis. Th i s inc rease in impor t s canno t be misconstrued for increase in fabrication demand as the imports of the metal have been largely gone into bonded warehouses a t por t s , or a t
exchange warehouses and is also used as collateral in order to get around at a time when lending costs were high. Hence, the import of the metal was not targeted to fabricators or for physical consumption by manufacturers. According to the current global economic environment, the demand scenario was not positive in the rest of Asia for 2011. According to WBMS data, refined copper consumption declined in India, South Korea and Taiwan by 22 percent, 12.7 percent and 14 percent respectively for 2011. But for current year, WBMS expects a return of growth by 2 to 5 percent in these three countries for the whole of 2012. On the supply front, world refined copper production growth had witnessed slow growth of 1.8 percent in last year from 3 percent growth in 2010. Due to some significant mine capacity additions on stream for current year, world refined copper supply is expected to increase by 3 percent. A comfortable supply scenario at a time of heightening global economic risks would be a negative for copper prices.
“We expect copper prices to trade on a negative note from the short-term perspec t i ve , as poor economic indicators” from world’s major economic coupled with the uncertainty surrounding the European debt crisis will act as a negative factor for the commodity.Keeping in mind a month’s view, we recommend a Sell in MCX Copper June contract around 415 – 420 with a Stop Loss of 432 and Ta r g e t o f 3 9 5 (CMP: 405)

TITANIUM AND TITANIUM
ALLOYS
INTRODUCTION TO TITANIUM
Titanium alloys are metals which contain a mixture of
titanium and other chemical elements it is the fourth
most abundant element in the Earth’s crust, the cost of
titanium is high due to its high melting point and
extreme reactivity. was discovered in Cornwall, Great
Britain, by William Gregor in 1791 and named by
Martin Heinrich Klaproth for the Titans of Greek
mythology. The element occurs within a number of
mineral deposits, principally rutile and ilmenite, which
are widely distributed in the Earth's crustand
lithosphere, and it is found in almost all living things,
rocks, water bodies, and soils. Titanium and titanium
alloys are attractive structural materials due to their
high strength, low density, and excellent corrosion
resistance. Titanium has high passivity; therefore it
exhibits high levels of corrosion resistance to most
mineral acids and chlorides. It is also nontoxic and
biologically compatible with human tissue and bone,
making it an ideal material for medical implant
products.
OVERVIEW OF TITANIUM AND ITS ALLOY
Titanium features a comparatively low density, simply
over 0.5 that of steel. It’s a comparatively low strength
when pure, however alloying offers a
substantial increase in strength.
Attributable to the low density of titanium, its alloys have
a high strength to weight ratio. It’s a high melting
purpose (1660°C) and wonderful corrosion resistance.
Pure titanium wrought products, which have minimum
titanium contents ranging from about 98% to 99.50%,
are used primarily for corrosion resistance. Titanium
products are also useful for fabrication but have
relatively low strength in service. The wrought product
forms of titanium and titanium-base alloys, which
include forgings and typical mill products, constitute
more than 70% of the market in titanium and titanium
alloy production. Powder metallurgy of titanium has not
gained wide acceptance and is restricted to space and
missile applications. The primary reasons for using
titanium-base products are its outstanding corrosion
resistance of titanium and its useful combination of low
density (4.5 g/cm3) and high strength. The strengths
vary from 480 MPa for some grades of commercial
titanium to about 1100 MPa for structural titanium alloy
products and over 1725 MPa for special forms such as
wires and springs. This allotropic behaviour, which
depends on the type and amount of alloy contents,
allows complex variations in microstructure and more
diverse strengthening opportunities than those of other
nonferrous alloys such as copper or aluminum.
The use of titanium has expanded in recent years to
include applications in nuclear power plants, food
processing plants, oil refinery heat exchangers, marine
components and medical equipments. The high cost of
titanium alloy components may limit their use to
Metalmentalist - June 201232
Titanium AlloysTitanium AlloysTitanium Alloys with Mr. Naveen Mathur, Associate Director-commodities & currencies, Angel Broking
applications for which lower-cost alloys, such as
aluminium and stainless steels. The relatively high cost
is often the result of the intrinsic raw material cost of
metal, fabricating costs and the metal removal costs
incurred in obtaining the desired final shape.
They are light weight, have extraordinary corrosion
resistance and the ability to withstand extreme
temperatures. However, the high cost of both raw
materials and processing limit their use to military
applications, aircraft, spacecraft, medical devices,
connecting rods on expensive sports cars and some
premium sports equipment and consumer electronics.
Branded Auto manufacturers also use titanium alloys in
engine components due to its durable properties in
these high stress engine environments.
Although "commercially pure" titanium has acceptable
mechanical properties and has been used for
orthopaedic and dental implants, for most applications
titanium is alloyed with small amounts of aluminum
and vanadium, typically 6% and 4% respectively, by
weight. This mixture has a solid solubility which varies
dramatically with temperature, allowing it to undergo
precipitation strengthening. This heat treatment
process is carried out after the alloy has been worked
into its final shape but before it is put to use, allowing
much easier fabrication of a high-strength product.
The combination of high strength-to-weight ratio,
excellent mechanical properties, and corrosion
resistance makes titanium the best material choice for
many critical applications. Today, titanium alloys are
used for demanding applications such as static
and rotating gas turbine engine components.
Some of the most critical and highly-stressed
civilian and military airframe parts are made
of these alloys.
TYPES OF TITANIUM ALLOYS
Commercially pure titanium alloys Commercially pure titanium alloys are
used primarily for corrosion resistance.
They are also useful in applications
requiring high ductility for fabrication but
relatively low strength in service. Yield
strengths range from 170 to 520 MPa.
Basically, oxygen and iron contents
determine the strength levels of commercially
pure titanium. In the higher-strength grades,
oxygen and iron are intentionally added to the residual
amounts already in the sponge to provide extra
strength. These are composed entirely of alpha part for
example of such an alloy - 92.5%, titanium - 5%,
aluminium - 2.5% tin each the aluminum and tin are
alpha stabilizers. Such alloys have the hexagonal
close-packed structure and, as a consequence, are
strong, maintain their strength at high temperatures
however is troublesome to figure. This kind of titanium
alloys have sensible weld ability and are used where
warm temperature strength is needed, e.g. turbine
blades. ALPHA AND NEAR-ALPHA ALLOYS
Alpha and near-alpha alloys contain aluminum as the
principal alloying element. Aluminum provides
solid-solution strengthening, oxidation resistance, and
reduces density. Other additions include the neutral
elements tin and zirconium, along with small amounts
of beta stabilizers. Alpha and near-alpha alloys are
slightly less corrosion resistant but higher in strength
than unalloyed titanium. They develop moderate
strengths and have good notch toughness. They have
medium formability and are weld able. Ti-5Al-2.5Sn is
the only true alpha alloy that is commercially produced.
The remainder of the commercially available alpha
and near-alpha alloys are near-alpha alloys.
Metalmentalist - June 201233
Titanium AlloysTitanium AlloysTitanium Alloys
Ti-5Al-2.5Sn is quite ductile, and the extra-low
interstitial grade retains ductility and toughness at
cryogenic temperatures. Because Ti-5Al-2.5Sn is a
single-phase alloy containing only alpha, it cannot be
strengthened by heat treatment. Near-alpha alloys
contain small amounts of beta phase dispersed in an
otherwise all-alpha matrix. The near-alpha alloys
generally contain 5 to 8 wt% Al. The near-alpha alloys
retain their strength to high temperatures and have
good creep resistance in the range of 320 to 590 °C
(600 to 1100 °F). These are composed of just about all
alpha part with little quantity of beta part dispersed
throughout the alpha. Such alloys are achieved by
adding tiny amounts, regarding one to twenty, or
beta-stabilizing parts like molybdenum and vanadium
to what's otherwise an alpha-stabilized alloy. An
example of such an alloy is ninetieth titanium. This alloy
is often utilized in the annealed condition. There are 2
types of annealing; mill annealing and duplex
annealing. Mill annealing involves heating the alloy to
790°C, soaking for eight hours and then furnace
cooling. Duplex annealing involves mill annealing
followed by reheating to 790°C, soaking for quarter of
an hour and then air cooling. The results of such
annealing are beta particles dispersed throughout an
alpha matrix. Titanium alloy within the annealed state is
employed for airframe and jet engine elements that
need high strengths, sensible creep resistance and
toughness up to temperatures of regarding 850°C. The
alloy has sensible weldability.
ALPHA-BETA ALLOYS
Alpha-beta alloys contain both the alpha and beta
phases. Again, aluminum is the principal alpha
stabilizer that strengthens the alpha phase. Beta
stabil izers, such as vanadium, also provide
strengthening and allow these to be hardened by
solution heat treating and aging. Alpha-beta alloys
have a good combination of mechanical properties,
rather wide processing windows, and can be used at
temperatures up to approximately 320 to 400 °C (600
to 750 °F). The alpha-beta alloys include Ti-6Al-4V,
which is the workhorse of the aerospace industry. It
accounts for approximately 60 wt% of the titanium used
in aerospace and up to 80 to 90 wt% of that used for
airframes. These contain sufficient quantities of
beta-stabilizing parts for there to be appreciable
amounts of beta part at area temperature. The
aluminum stabilizes the alpha part whereas the
vanadium stabilizes the beta part. These alloys will be
answer treated, quenched and aged for increased
strength. The micro structure of the alloys depends on
their composition and warmth treatment. Thus, a quick
cooling rate from a temperature where the fabric was
all, beta, e.g. quenching in cold water, produces a
martensitic structure with some increase in hardness.
Ageing will then turn out some any increase in strength
as results of beta precipitates.
BETA ALLOYS
A typical beta-t i tanium al loy contains 77%
t i tanium-13% vanadium-11% chromium-3%
aluminum. Beta alloys are sufficiently rich in
beta stabilizers and lean in alpha stabilizers
that the beta phase can be
completely retained with
appropriate cooling rates.
Beta alloys contain
smal l amounts of
a lpha- s tab i l i z i ng
e l e m e n t s a s
strengthening agents.
As a class, beta and
near-beta alloys offer
i n c r e a s e d f r a c t u r e
toughness over alpha-beta
alloys at a given strength level.
B e t a a l l o y s a l s o e x h i b i t b e t t e r
room-temperature forming and shaping

than alpha-beta alloys at temperatures where yield
strength instead of creep strength is the requirement,
and better response to STA in heavier sections than the
alpha-beta alloys. They are limited to approximately
370 °C (700 °F) due to creep. When sufficiently high
amounts of beta-stabilizing parts are added to
titanium, the ensuing structure will be created entirely
beta at area temperature when quenching, in some
cases by air cooling In contrast to alpha-titanium alloys.
Beta-titanium alloys are readily cold worked within the
answer treated and quenched condition, and may be
subsequently aged to relinquish terribly high strengths.
Within the high-strength condition the alloys have low
ductility’s. They’ll additionally suffer from poor fatigue
performance. The alloys are therefore not thus widely
used because the alpha-beta alloys. The alloy is
sometimes utilized in the answer treated, quenched
and aged condition so as to get the terribly high tensile
strength. It’s used for aerospace elements, honeycomb
panels and high strength fasteners aviation-database

TITANIUM NEWS
Kobe Steel expanding titanium capacityTOKYO, Kobe Steel, Ltd. announces that it plans to
increase its production capacity of titanium alloys for
the aerospace sector and commercially pure titanium
for general
industry. Investments
are anticipated to total 7.5
billion yen, of which 1.5 billion
yen is allocated for the joint venture
Japan Aeroforge, Ltd.Kobe Steel plans to construct a new ring rolling mill and
install heat treatment and inspection equipment for
large forged products at its Takasago Works in
Takasago, Hyogo Prefecture in western Japan. Group
company Kobe Special Tube Co., Ltd., a 100% owned
subsidiary of Kobe Steel, has already completed a
titanium welded tube line in Shimonoseki, Yamaguchi
Prefecture, also in western Japan.Titanium demand is anticipated to expand over the
medium- to long-term future owing to strong worldwide
demand for civilian aircraft and infrastructure demand
in emerging countries, such as for power generation
and desalination plants. Japan's total shipments of
titanium mill products reached 19,358 metric tons in
2011 (ended December 2011), the second highest
since 2008. Of this amount, a record 13,245 metric
tons were exported.Through the capital investments, Kobe Steel will be able
to increase and improve its production capacities for
ring products for aircraft and large forgings made of
titanium alloys, as well as welded tube made of
commercially pure titanium. The additional capacity
will enable Kobe Steel to enhance business
opportunities for the growing titanium market.In September last year, Kobe Steel developed precoated
titanium sheet and high heat transfer titanium sheet for
Metalmentalist - June 201235
use in plate heat exchanger. Expanding its production
capacity and strengthening its ability to meet user
needs, Kobe Steel's Titanium Division plays an
important role in contributing to the company's
medium- to long-term business vision, KOBELCO
VISION "G.”
Kobe Steel pioneered the production and commercial
application of titanium in Japan, when in 1949 it
became the first company to begin research on this
lightweight material. Kobe Steel is Japan's only
integrated producer of titanium mill products with
operations ranging from melting to mill product
manufacturing. The company supplies numerous
titanium products to a wide variety of industries.
1. Construction of new ring rolling mill at Takasago
WorksAs the current ring rolling mill at Takasago Works is over
20 years old and aging, Kobe Steel decided to build a
new ring rolling mill. By installing new equipment for
high precision rolling, Kobe Steel can utilize
near-net-shape ring rolling and achieve a considerable
reduction in forging weight. This is anticipated to
reduce costs and increase orders for rings used in jet
engines. By constructing the new ring rolling mill, Kobe
Steel's ring rolling capacity is anticipated to double. The
current ring rolling mill will be shut down after the new
mill receives certification.
2. Installation of heat treatment and inspection
equipment for large forgings at Takasago WorksKobe Steel plans to install heat treatment and
inspection equipment for large forgings to be
manufactured by Japan Aeroforge, Ltd., a joint venture
with Hitachi Metals, Ltd. and other partners. This
investment will expand sales to domestic heavy industry
manufacturers of large titanium forgings.
In the future, Japan Aeroforge hopes to provide
overseas aircraft manufacturers with forgings. The heat
treatment and inspection equipment to be installed is
aimed at meeting processing capacity, as well as
specifications from aircraft manufacturers. Production
capacity will increase three-fold.
Titanium billets made at the Takasago Works will be
supplied to Japan Aeroforge for die forging. The
semifinished forgings will then be returned to Takasago
for heat treatment and inspection before being shipped
to customers.
3. Expansion of titanium welded tube line at Kobe
Special Tube Co., Ltd.Kobe Special Tube added a new line at Japan's largest
titanium welded tube plant. The added capacity will
help meet the growing demand for welded tube for
power plants in emerging countries and desalination
plants in the Middle East.
The new line enables Kobe Steel Tube to gain more
orders by providing the additional capacity necessary
for large projects. Integrated production from ingot
melting to welded tube manufacturing enables the
Kobe Steel Group to supply high-quality titanium
welded tube. This investment increased production
capacity 25 to 30%.
To bolster the annealing capacity of the base material
for the new welded tube line at Kobe Special Tube, Kobe
Steel increased the capacity of its vacuum annealing
equipment for sheet at its Kakogawa Works in
Kakogawa Hyogo Prefecture. The new line went into
operation in December 2010.

COPPER AND COPPER ALLOYS
OVERVIEW
It was originally named cyprium (metal of Cyprus)
Cyprus initially during the Romanian time as it was
mined in Cyprus. Later the name was shortened to
cuprum. Copper is known as the Best conductor of
Electricity. It has been a best friend of human being as
oldest civilization knew its usage more than 10,000
years ago. It is the most common and important metals
having a wide scope of applications in many sectors
across the world such most importantly in Electrical,
Manufacturing, Aerospace, Heat exchanger,
Telecommunications and utensils. Copper is known for
its super conductivity, high ductility, corrosion resistant
and easy moulding properties. It is vital to humans.
Adults require 2-3 mg copper in their diet daily. There
are as many as 400 different copper and copper-alloy
compositions loosely grouped into the categories such
as copper, high copper alloy, brass, bronze, copper
nickels, copper–nickel–zinc (nickel silver) and leaded
copper and special alloys. They are amongst the most
necessary materials needed to provide the means to
keep home, commerce and industry running. The best
known traditional types are bronze; where tin is a
significant addition, and brass, using zinc instead. Most
of its uses are based on this property or the fact that it is
also a good thermal conductor.
TYPES OF COPPER ALLOYS
COPPER ALLOYS
These alloys have excellent resistant to sea water
corrosion and are good conductor of electricity as well
as have a higher strength resistant, have similar
corrosion resistance, but they are susceptible to
corrosion at high water velocities. The high-copper
alloys are primarily used in applications that require
enhanced mechanical performance, often at slightly
elevated temperature, with good thermal or electrical
conductivity. There are various grades of unalloyed
copper, which differ in the amount of impurities they
contain. Oxygen free coppers are used specifically in
applications requiring high conductivity and
exceptional ductility.
BRASSES
Brasses containing between 32% and 39% zinc exhibit
excellent hot working characteristics but limited cold
workability .Brass colour ranges from red to golden
yellow, depending on the amount of zinc the alloy
contains. Gilding Metal, Commercial Bronze, Jewellery
Bronze, Red Brass and Cartridge Brass are common
names given to brass alloys with specific zinc contents.
Brasses containing more than 39% zinc have high
strength and lower ductility at room temperature than
alloys with less zinc. Elements such as lead, tellurium,
beryllium, chromium, phosphorus, and manganese
have little or no effect on the corrosion resistance of
coppers and binary copper-zinc alloys. These elements
are added to enhance such mechanical properties as
machining ability, strength, and hardness. Brass are
alloys made from copper and zinc, they exhibit good
strength and ductility and are easily cold worked,
properties which improve with increased zinc content
up to 35%. Brasses are known for their ease of
fabrication by drawing, high cold-worked strength and
corrosion resistance. Brasses are routinely blanked,
coined, drawn and pierced to produce springs, fire
extinguishers, jewellery, radiator cores, lamp fixtures,
ammunition, flexible hose and the base for gold plate.
Brasses have excellent cast ability. Cast brasses are
used as plumbing fixtures, decorative hardware,
architectural trim, low pressure valves, gears and
bearings are basically copper-zinc alloys and are the
most widely used group of copper alloys.
Metalmentalist - June 201238
Copper AlloysCopper AlloysCopper Alloys
TIN BRASSES
They possess good hot forge ability and good cold
formability. These materials have moderate strength;
high atmospheric and aqueous corrosion resistance
and excellent electrical conductivity. Cast brasses for
marine applications are also modified by the addition
of tin, lead, and, sometimes, nickel. This group of alloys
is known by various names, including composition
bronze, ounce metal, and valve metal. Tin Brasses
alloys made are made from copper with zinc content
ranging from 2 % to 40% and tin from 0.2% to 3%. This
family of alloys includes admiralty brasses, naval
brasses and free-machining tin brasses. These alloys
are used to make high-strength fasteners, electrical
connectors, springs, corrosion resistant mechanical
products, marine hardware, pump shafts, and
corrosion-resistant screw machine parts.
ALUMINUM BRONZES
Aluminium Brasses containing 5 to 12% Aluminium
have excellent resistance
to resisting corrosion and
h i g h - t e m p e r a t u r e
oxidation. High copper
alloys aluminum
containing alloys
can be quenched
and tempered. Aluminum bronzes are used in marine
hardware, shafts and pump and valve components for
handling seawater; sour mine waters, non oxidizing
acids, and industrial process fluids. They are also used
as heavy duty sleeve bearings and machine tool ways.
Aluminum bronzes are used for beater bars and for
blades in wood pulp machines because of their ability
to withstand mechanical abrasion and chemical attack
by sulfite solutions. Aluminum bronze castings have
exceptional corrosion resistance, high strength,
toughness and wear resistance. They also exhibit good
casting and welding characteristics. In the most of
practical commercial applications, the corrosion
characteristics of aluminum bronzes are primarily
related to aluminum content. Alloys with up to 8% Al
normally have completely face-centred cubic structures
and a good resistance to corrosion attack. Solid
solution strengthening, cold work and precipitation of
an iron rich phase contribute to these characteristics.
Nickel appears to alter the corrosion characteristics of
the phase to provide greater resistance to de alloying
and cavitations-erosion in most liquids.
NICKEL SILVERS
Though they do not contain silver, they
have an a t t rac t i ve s i l ver lus te r,
moderately high strength and good
corrosion resistance. The two most
common nickel silvers are C75200 and
Metalmentalist - June 201239
Copper Alloys Copper Alloys Copper Alloys
they have good resistance to corrosion in both fresh
and salt waters. Nickel Silvers are also called nickel
brasses which contain copper, nickel, and zinc. They
are used to make food and beverage handling
equipment, decorative hardware, electroplated
tableware, optical and photographic equipment and
musical instruments.Primarily because their relatively
high nickel contents inhibit dezincification, C75200
and C77000 are usually much more resistant to
corrosion in saline solutions than brasses of similar
copper content.
PHOSPHOR BRONZES
Phosphor bronzes have superb spring qualities, high
fatigue resistance, and excellent formability and solder
ability, and high corrosion resistance. They are used
primarily for electrical products; other uses include
corrosion resistant bellows, diaphragms and spring
washers. Phosphor Bronzes alloys in Addition of tin and
phosphorus along with copper produces good
resistance to flowing seawater and to most non
oxidizing acids except hydrochloric. Alloys containing 8
to 10% stannum have high resistance to impingement
attack. Phosphor bronzes are much less susceptible
than brasses and are similar to copper in resistance to
sulfur attack. Tin bronzes-alloys of copper and tin-tend
to be used primarily in the cast form, in which they are
modified by further alloy additions of lead, zinc, and
nickel. Phosphor Bronzes, or tin bronzes as they are
sometimes called, contain between 0.5% and 11% tin
and 0.01% to 0.35% phosphorous. Tin increases their
corrosion resistance and tensile strength; phosphorous
increases wear resistance and stiffness.
COPPER NICKELS ALLOYS
The common copper nickel alloys are known as 70/30,
90/10 which has the best general resistance to
aqueous corrosion of all the commercially important
copper alloys. Both of these alloys, although well suited
to applications in the chemical industry, have been most
ex tens ive l y used for condenser tubes and
heat-exchanger tubes in recalculating steam systems.
They are superior to coppers and to other copper alloys
in resisting acid solutions and are highly resistant to
corrosion. Copper alloys possess tensile properties that
exceed some aluminum alloys and approach those of
stainless steels, and can be used in a multitude of
applications. Copper is a relatively soft and malleable
metal with excellent formability, making it ideal for
architectural applications such as roofs, wall cladding,
gutters and downspouts. Additions of other elements to
copper strengthen it and form copper alloys, including
brasses, phosphor bronzes and copper nickels.
Miniaturization of electronic devices and components
has benefited from the high strength and moderate to
high conductivities offered by specialty copper alloys.
COPPER AND ITS ALLOYS USAGE
STRUCTURE.
ELECTRICAL APPLICATIONS
Approximately 65% of copper produced is used for
electrical applications. Copper has the highest
electrical conductivity of any metal, apart from silver,
leading to applications in generators, transformers,
motors, bus bars and cables provide and deliver
electricity safely and efficiently to homes and
businesses. Copper has a key role to play in energy
efficiency - the judicious use of 1 tonne of copper in the
energy sector makes it possible to reduce CO2
emissions by 200 tonnes per year on average.

CHEMICAL ANALYSISA report of the chemical composition of
thee elements, and their percentage
that form a stainless steel product.
CHROMIUM(CR) An alloying element that is used in
stainless steel to deter corrosion.
COATINGThe process of covering steel with
another material (tin, chrome, zinc
etc.), primarily for corrosion resistance. They can be classified as anodic, cathodic and inert.
COILSSteel sheet that has been wound. A slab, once rolled in a hot-strip mill, is more than one-quarter mile long; coils
are the most efficient way to store and transport sheet steel.
COILINGThe process of laying or winding the product in the form of coils
COILED BARA long length of hot rolled bar produced in a continuous
rolling mill and coiled in a manner similar to wire rod.
COLD DRAWINGReducing the cross-sectional area of a tube, when cold, by
drawing through a die. The tubes are occasionally pushed
through the die.
COLD-ROLLED STRIP (SHEET)A product manufactured from hot rolled descaled (pickled)
coils by cold reducing to the desired thickness, generally
followed by annealing and temper rolling. Strip has a final
product width of approximately 12 inches, while sheet may be
more than 80 inches wide. Cold-rolled sheet is considerably
thinner and stronger than hot-rolled sheet, so it will sell for a
premium. If the sheet is not annealed after cold reduction it is
known as full hard.

GlossaryGlossaryGlossary
CONDENSER TUBESTubes used in the conversion of a vapour into a liquid by cooling.
CONTINUOUS CASTINGWhat A method of pouring steel directly from the furnace into a semi-finished product
such as billet, bloom, or slab directly from its molten form. It bypasses the traditional
process of pouring (teeming) molten steel into ingots, reheating those ingots, and
then rolling them into semi-finished steel shapes.
Why Continuous casting avoids the need for large, expensive mills for rolling ingots
into slabs. Continuous cast slabs also solidify in a few minutes versus several hours for
an ingot. Because of this, the chemical composition and mechanical properties are more
uniform. This process has steadily displaced ingot casting due to its advantages of higher
yield and improved productivity.
How Steel from the BOF or electric furnace is poured into a tundish (a shallow vessel that looks like a bathtub)
atop the continuous caster. As steel carefully flows from the tundish down into the water-cooled copper mould
of the caster, it solidifies into a ribbon of red-hot steel. At the bottom of the caster, torches cut the continuously
flowing steel to form slabs or blooms.
COPPERED WIREA wire produced by wet drawing with a copper sulphate or copper tin sulphate solutions for improving
drawability. The colour depends upon the chemical used and the drawing operation imparts a luster to the wire
resulting into improved appearance and limited corrosion resistance.
CORROSIONThe gradual degradation or alteration of steel caused by chemical or electrochemical attack due to
atmosphere, moisture, or other agents.
CORROSION RESISTANCEThe intrinsic ability of a material to resist degradation by corrosion. This ability can be
enhanced by application of special coatings on the surface of the material or by
imparting certain structural changes in the material by addition of alloying elements.
CUT-TO- LENGTHCutting flat-rolled stainless steel into desired length and then normally shipped
flat-stacked.
DEFORMED BARConcrete reinforcing bars in which the surface is provided with lugs or protrusions (called
deformations) which inhibit longitudinal movement of the bars relative to the
surrounding concrete. The surface deformations are hot formed in the final roll pass by
passing the bars between rolls having patterns cut into them so that the surfaces of the
bars are forced into the depressions in the rolls to form characteristic deformations.
DUPLEXA category of stainless steel with high amounts of chromium and moderate nickel
content. The duplex class is so named because it is a mixture of austenitic (chromium-
nickel stainless class) and ferritic (plain chromium stainless category) structures. This
Metalmentalist - June 201248
GlossaryGlossaryGlossary
combination was originated to
offer more strength than either of
those stainless steels. Duplex
stainless steels provide high resistance to
s tress corrosion cracking
(formation of cracks caused by
a combination of corrosion
and stress) and are suitable
f o r h e a t e x c h a n g e r ’ s ,
desalination plants, and
marine applications.
ELECTRIC RESISTANCE WELDED (ERW) PIPEPipe made from strips of hot-rolled steel which are is formed into tubular shape by passing through forming
rolls and welded by passing a heavy current across the longitudinal joint. While seamless pipe is traditionally
stronger and more expensive than comparable ERW pipe, ERW technology is improving and the technique now
accounts for approximately 48% of OCTG shipments by tonnage. Generally used by oil or gas companies.
ELECTROLYTIC TIN PLATE (ETP)1. Light-gauge, low-carbon, cold reduced steel on which tin has been electro-deposited.
2. Black plate coated with Tin (Sn) electron deposition.
ELECTROPLATINGThis process is an old art, practiced not only to protect the base metal from corrosion
but also for decorative purposes and, more recently, to protect the base metal from
wear by friction or abrasion. Metals used for coatings include cadmium, chromium,
copper, gold, tin, lead, nickel, silver and zinc, and alloys such as brass, bronze and lead-
tins as well as cobalt-tungsten, tungsten-nickel, nickel-zinc and cadmium-tin alloys.
ELONGATIONA measurement of ductility expressed in terms of the stretch having occurred over a given length on a standard
tensile specimen at time of fracture, usually based an original length of 2 inches.
EXTRUSIONHot Extrusion : Consists of enclosing a piece of metal, heated to forging temperature, in a chamber called a
'container' and having a die at one end with an opening of the shape of the desired finished section, and
applying pressure to the metal through the opposite end of the container. The metal is forced through the
opening, the shape of which it assumes in cross-section as the metal flows plastically under the great used.
Cold Extrusion : It is carried out in a manner similar to the hot-extrusion process, with two main exceptions :
(1) The steel is at room temperature, and (2) the surface of the piece is treated by some chemical process such
as bonderizing to assist in reducing the friction between the steel and the container wall and die, in conjunction
with special lubricants.
FERRITICThe second-largest class of stainless steel, constituting approximately 25% of stainless production. Ferritic
stainless steels are plain chromium steels with no significant nickel content; the lack of nickel results in lower
Metalmentalist - June 201249
GlossaryGlossaryGlossary
corrosion resistance than the austenitics (chromium-nickel stainless steels). Ferritics are best suited for general
and high-temperature corrosion applications rather than services requiring high strength. They are used in
automotive trim and exhaust systems, interior architectural trim, and hot water tanks. Two of the most common
grades are type 430 (general-purpose grade for many applications, including decorative ones) and type 409
(low-cost grade well suited to withstanding high temperatures).
FERROALLOYA metal product commonly used as a raw material feed in steel making, usually
containing iron and other metals, to aid various stages of the steel making process
such as deoxidation, desulfurization, adding strength or for introducing such
elements in steel. Examples: ferrochrome, ferromanganese, and ferrosilicon, silicon
manganese etc.
FERROCHROMEAn alloy of iron and chromium with up to 72% chromium. Ferrochrome is commonly
used as a raw material in the making of stainless steel.
FERROUSMetals that consist primarily of iron.
FLAT ROLLED STEELSteel produced on rolling mills utilizing relatively smooth, cylindrical rolls. The width to
thickness ratio of flat rolled products is usually fairly large. Examples of flat rolled
steel are hot-rolled, cold-rolled, and coated sheets and coils, tin mill products, etc.
FLEXIBILITYThe quality or state of a material that alloys it to be flexed or bent repeatedly without
undergoing fracture.
FOILMetal with a maximum width of .005 inches.
FORGING Forming a hot or cold metal into fixed shape by hammering, upsetting, or pressing.
GALVANIZED STEELSteel coated with a thin layer of zinc to provide corrosion resistance in underbody auto parts, garbage cans,
storage tanks, or fencing wire. Sheet steel normally must be cold-rolled prior to the galvanizing stage.Hot-dipped. Steel is run through a molten zinc coating bath, followed by an air stream
"wipe" that controls the thickness of the zinc finish.Electro-galvanized. Zinc plating process whereby the molecules on the positively
charged zinc anode attach to the negatively charged sheet steel. The thickness of the
zinc coating is readily controlled. By increasing the electric charge or slowing the speed
of the steel through the plating area, the coating will thicken.Differences. Electro-galvanizing equipment is more expensive to build and to operate
than hot dipped, but it gives the steel maker more precise control over the weight of the
zinc coating. The automotive manufacturers, because they need the superior welding,
forming and painting ability of electro-galvanized steel, purchase 90% of all tonnage
produced.

GlossaryGlossaryGlossary
GAUGEThe thickness of certain stainless steel.
HARDENABILITYThe relative ability of a ferrous alloy to form
martensite when quenched from a temperature
above the upper cr i t ical temperature.
Hardenability is commonly measured as a
distance below a quenched surface at which the
metal exhibits a specific hardness– 50 HRC, for
example- or a specific percentage of martensite in
the micro-structure.
HARDENINGIncreasing hardness by suitable treatment, usually
involving heating and cooling. See also age
hardening, case hardening, induction hardening,
precipitation hardening, and quench hardening.
HARDNESSA measure of the resistance of a material to surface
indentation or abrasion; may be thought of as a function of the stress required to produce some specified type
of surface deformation. There is no absolute scale for hardness; therefore, to express hardness quantitatively,
each type of test has its own scale of arbitrarily defined hardness. Indentation hardness can be measured as
Brinell, Rockwell, Vickers, Knoop, and Scleroscope hardness tests.
HEAT EXCHANGER TUBESTubes used in a unit for the purpose of transferring heat from one medium to another.
HIGH CARBON STEELCarbon steel containing generally more than 0.6% carbon. The more carbon that is dissolved in the iron, the
less formable and the tougher the steel becomes. High-carbon steel's hardness makes it suitable for plow
blades, shovels, bedsprings, cutting edges, or other high-wear applications.
IRON OREMineral containing enough iron to be a commercially viable source of the element for
use in steel making. Except for fragments of meteorites found on Earth, iron is not a
free element; instead, it is trapped in the earth's crust in its oxidized form. It is of two
types : containing ferric oxide (Hematite) or ferro-ferric oxide (Magnetite).
LOW-CARBON STEELSteel with less than 0.005% carbon is more ductile (malleable): It is
capable of being drawn out or rolled thin for use in automotive body applications.
Carbon is removed from the steel bath through vacuum degassing.
MACHINABILITYThe capability of being machined. It is controlled through the composition and rate of
cooling, but often must be sacrificed for some more essential property, such as
strength or toughness.

GlossaryGlossaryGlossary
MAGNET STEELSThese are an example of alloy electrical steels. The outstanding property of these steels
is their retentivity or ability to retain magnetism. Cobalt, chromium, and tungsten are
the alloying elements commonly used to enhance this characteristic.
MARTENSITICSmall category of stainless steel characterized by the use of heat treatment for
hardening and strengthening. Refers to a particular grain structure of steel which is
extremely hard and consists of iron oxide precipitates in a ferrite matrix. Martensitic stainless
steels are plain chromium steels with no significant nickel content. They are utilized in equipment for the
chemical and oil industries and in surgical instruments. The most popular martensitic stainless steel is type 410
(a grade appropriate for non-severe corrosion environments requiring high strength).
MEDIUM-CARBON STEELCarbon steel containing generally minimum of 0.30% carbon and maximum 0.60% carbon.
MELTA stage in the steel making process when all the scrap charged has been melted. This
term is also synonymous with cast, blow or heat.
MILD STEELCarbon steel containing generally less than 0.30% carbon.
MOLYBDENUM (MO)An alloying element used as a raw material for some classes of stainless steel.
Molybdenum in the presence of chromium enhances the corrosion resistance of stainless steel.
MULTIPLE LENGTHSLength from which a given number of pieces of specific lengths can be cut with minimum
waste.
NICKEL(NI)An alloying element used as a raw material for certain classes of stainless steel. Nickel
provides high degrees of ductility (ability to change shape without fracture) as well as
resistance to corrosion. Approximately 65% of all nickel is used in the making of
stainless steel.
PIG IRONThe name for the melted iron produced in a blast furnace, containing a large quantity of carbon (above 1.5%,
usually between 3% to 4.5%), along with silicon, manganese, phosphorus, and sulphur in varying amounts
depending upon the quality of raw materials used and solidified in moving metal moulds of a Pig Casting
Machine. Pig iron is used in the foundry or for conversion into steel. Named long ago when molten iron was
poured through a trench in the ground to flow into shallow earthen holes, the arrangement looked like
newborn pigs suckling. The central channel became known as the "sow," and the moulds were "pigs.”
PIPE1. Technically a tube used to transport fluids or gases. However, pipe and tube are often used interchangeably
in steel lexicon, with a given label applied primarily as a matter of historical use.2. An axial cavity caused by contraction during solidification of an ingot. Also the defects arising from the axial
cavity on the semi-finished or finished products.

GlossaryGlossaryGlossary
PLATEA hot or cold rolled flat product, rolled from an ingot or slab in
rectangular cross section with a width 600mm and above and a thickness
5mm and above (going upto one foot).
PRIME COILAny coil produced by the line that is not held for any out-of-spec or quality
reasons.
PROCESS ANNEALINGA heat treatment used to soften metal for further cold working. In ferrous sheet and wire industries, heating to a
temperature close to but below the lower limit of the transformation range and subsequent cooling for working.
In the non-ferrous industries, heating above the recrystalization temperatures at a time and temperature
sufficient to permit the desired subsequent cold working.
REINFORCING BAR (REBAR)A commodity-grade steel used to strengthen concrete in highway and building construction.
RESISTANCE HEATINGHeating of steel by passing current through solid conductors and using the heat generated as a result of the
conductors’ inherent resistance to the flow of current. It can be applied through three methods :1. The indirect method, in which the steel is heated by radiation and convection from resistors through which
the current is passed.2. The direct method in which the current is passed directly from a power source through
the metal.3. The induction method in which the current is induced in the steel by an induction
coil connected to the power supply.Neither the indirect nor the direct method of resistance heating is practical for
steel-making operations. However, the induction method is employed successfully in
special steel-melting operations.
SCRAP (FERROUS)Ferrous (iron-containing) material that generally is re-melted and recast into new steel. Integrated steel mills
use scrap for up to 25% of their basic oxygen furnace charge; 100% of the mini-mills' raw material for their
electric furnaces generally is scrap.Home (Revert) Scrap Waste steel that is generated from within the steel mill, through edge trimming, rejects and
metallic losses in slag. It normally is sent directly back to the furnace.Prompt (Industrial) Scrap Excess steel that is trimmed by the auto and appliance stampers and auctioned to
scrap buyers as factory bundles. This is a high-quality scrap as the result of its low-residual content and
consistent chemistry.Obsolete (Reclaimed) Scrap Iron-bearing trash. Automobile hulks, worn-out
refrigerators and useless storage tanks, for example, can be recovered from the
junkyard and re-melted. The residual impurity of such scrap normally relegates
obsolete scrap to the mini-mills (see No. 1 Heavy Melt).
SCREW STOCKFree cutting steel bars suitable for the manufacture of bolts and screws.
Metalmentalist - June 201253
GlossaryGlossaryGlossary
SEAMLESS PIPEA pipe without a longitudinal joint or weld, made from a solid billet, which is heated, then rotated under
extreme pressure. This rotational pressure creates an opening in the center of the billet,
which is then shaped by a mandrel to form pipe.
SECONDARY STEELSteel that does not meet the original customer's specifications because of a defect in
its chemistry, gauge or surface quality. Mills must search to find another customer
(that can accept the lower quality) to take the off-spec steel at a discount. While
secondary will not affect the reported yield, margins will suffer.
SECONDARY STEEL MAKINGThe purpose of secondary steel making is to produce ‘clean’ steel, steel which satisfies stringent requirements
of surface, internal and micro-cleanliness quality and of mechanical properties. Ladle metallurgy is a
secondary step of the steel making process often performed in a ladle after the initial refining process in a
primary furnace is completed.
SHEETA hot or cold-rolled flat product, rolled in rectangular sections of thickness below 5 mm and
supplied in straight lengths. The width is at least 100 times the thickness and the edges
can be mill trimmed, sheared or flame cut. A sheet can also be obtained by
cutting of strips.
SHEET BAR (SLAB BAR)Semi-finished product of rectangular section, of thickness
not less than 6mm and width not less than 150mm, and of
such dimensions that the thickness does not exceed
one-fourth of the width. This term also includes tin
plate bars.
SHEET PRODUCTS1. Hot Rolled : Uncoated, heavy gauge, fully
processed in Strip Steel, never cold reduced at Tandem
Mill.
2. Cold Rolled : Uncoated, heavy gauge, primarily
processed in Strip Steel, although some goes to the Tin
Mill, always cold reduced at Tandem Mill.
3. Galvanized : "Bath" coated with zinc, heavy gauge,
primarily processed through Strip Steel & Sheet Mill,
majority is cold reduced at Tandem Mill.
4. Electro-galvanized : Zinc coated, normally lighter
gauge than galvanized, processed through Strip Steel & Tin Mill,
mostly single reduced. (Tandem)
SPECIAL BAR QUALITY (SBQ)SBQ represents a wide variety of higher-quality carbon and alloy bars that are used in the forging,
machining and cold-drawing industries for the production of automotive parts, hand tools, electric motor
shafts and valves. SBQ generally contains more alloys than merchant quality and commodity grades of steel
bars, and is produced with more precise dimensions and chemistry.

SPECIAL STEELSteel in the production of which special care has to be taken so as to attain the desired cleanliness,
surface quality and mechanical properties.
SPECIALTY TUBERefers to a wide variety of high-quality custom-made tubular products requiring
critical tolerances, precise dimensional control and special metallurgical
properties. Specialty tubing is used in the manufacture of automotive,
construction and agricultural equipment, and in industrial applications
such as hydraulic cylinders, machine parts and printing rollers. Because
of the range of industrial applications, the market typically follows
general economic conditions.
SPONGE IRONIron obtained by solid state reaction. In this process, iron is not melted.
For many centuries before blast furnace was developed around 1300 AD,
sponge iron provided the main source of iron and steel. It was produced in
relatively shallow hearths or in shaft-furnaces, both of which used charcoal as
fuel. The product of these early smelting processes was a spongy mass of
coalesced granules of nearly pure iron intermixed with considerable slag. Usable
articles of wrought iron were produced by hammering the spongy mass, while still hot from the smelting
operation, to expel most of the slag and compact the mass. By repeated heating and
hammering, the iron was further freed of slag and forged into the desired shape.
TEMPERA condition produced in a metal or alloy by mechanical or thermal treatment and
having characteristics structure and mechanical properties. A given alloy may be in
the fully softened or annealed temper, or it may be cold worked to the hard temper, or further to spring temper. Intermediate tempers produced by cold working
(rolling or drawing) are called "quarter-hard", "half-hard" and "three quarters hard", and
are determined by the amount of cold reduction and the resulting tensile properties. In addition
to the annealed temper, conditions produced by thermal treatment are the solution heat-treated temper and
the heat-treated and artificially aged temper. Other tempers involve a combination of mechanical and thermal
treatments and include that temper produced by cold working after heat treating, and that produced by
artificial aging of alloys that are as-cast, as-extruded, as-forged and heat treated, and worked.
TOLERANCESA customer's specifications can refer to dimensions or to the chemical properties of steel
ordered. The tolerance measures the allowable difference in product specifications
between what a customer orders and what the steel company delivers. There is no
standard tolerance because each customer maintains its own variance objective.
Tolerances are given as the specification, plus or minus an error factor; the smaller
the range, the higher the cost.
TOOL STEELSSteels that are hardened for the use in the manufacture of tools and dies.

TUNGSTEN (W)Gray metal with high tensile strength. It is ductile, malleable, and resistant
to atmospheric elements and all acids except strong alkalies.
WIDTHThe lateral dimensions of rolled stainless steel, as opposed to the gauge. If
width of the stainless steel strip is not controlled during rolling, the edges
must be trimmed .
WIREA finished product, round, half round, square, hexagonal, flat or of any
other section including grooved section characterised by the fact that it has
been subjected to a sizing operation at ambient temperature by the process of
drawing through a die or by other mechanical means. Wire is generally supplied in
coil form but in exceptional cases can be supplied in straight lengths.
YIELD STRENGTHThe stress beyond which stainless steel undergoes important permanent
flow-commonly specified as that stress producing a 0.2% offset from the
linear portion of the stress-strain curve.
ZIRCONIUM (ZR)A strong, ductile metal obtained by the chemical
processing of zircon-bearing sands. It has
good corrosion resistance at high
temperatures and is used as a structural
material in nuclear reactor and cladding
material for uranium.
