Quality is not just passable,

its Paramount.

SPECIAL STEELS

Kadimi Special Steels is a leading steel company in India.

We are an Indo-Japanese joint venture between Kadimi

and Nakagawa Steel.

Our plant is located in Sriperumbudur, 25 kms from the

port of city of Chennai. We are the largest automated steel

processing plant for wire rods in India and have an annual

capacity of 84,000 MT.

We offer high quality Steel Wires that are used in the

production of automotive fasteners, cold forged

component, bearings, chains and springs.

We accomplish our supreme quality by combining state-of-

the-art equipment along with Japanese commitment to

quality.

With our goal of manufacturing the ultimate quality wire,

we constantly innovate to have the best manufacturing

practices in the country.

Our conviction and latest technologies along with our

commitment to the environment have led us to make our

plant a zero-dischargefacility. Thus, all our products are

manufactured under the most eco-friendly conditions.

Capacity: Automated pickling and coating line of 84000MT/ annum

During the pickling process, several surface treatments can be executed. The line is fully

equipped with cleaning, pickling and phosphating as well as lime and double lime baths.

This means that a large number of surface treatments can be applied to all types of

wires as untreated, annealed and drawn wire.

Pickling and Coating

AnnealingOur customized bell type Hydrogen annealing furnaces assures uniformity of temperature and atmosphere to produce

consistent properties that are required in CHQ wire. The spheroids are structurally consistent due to uniform temperature

in the furnace, secured by high convection which is possible due to gas with good heat conductivity and high speed fans.

The furnace's special AC/APEX system guarantee complete spherodization and protection against decarburization.

We have the largest annealing batch capacity with the lowest cycle times in the country. This allows us to meet urgent

demands of our customers.

Wire DrawingWe have a wire drawing capacity of 40000MT/ year

ranging from sizes 4.5-33m.

We have provisions for eddy current testing to supply

crack free material to our customers.

Quality AssuranceOur policy is to provide a system of continuous improvement

in all aspects of our business. All our measuring instruments

are sourced from Japan to ensure high precision. All quality

checks and testing equipment are designed in order to ensure

compliance with strict automotive standards set in Japan.

In addition to chemical analysis verification, comprehensive in-house testing facilities enable us to offer:

! Tensile Strength Tests

! Hardness and Roughness Tests

! In line Eddy Current Tests

! Upset Tests

! Metallographic Structure Tests

! Elongation and Reduction of Area Tests

Our plant is fully environmentally compliant. Our

constant innovation and commitment to the

environment has led us to use best practices to

create a zero discharge facility. We are sparing no

efforts to surpass the environmentally friendly

standards. We are able to reuse 95% of the water

that we use in this process.

For special requirements of steel products, the final physical properties required of materials cannot

be achieved through the chemical composition of the steel alone. With our innovative heat

treatment and surface treatment capabilities, we are able to accord our products precisely the

usage properties they need for their subsequent applications.

Surface Treatment

We are supplying the heat-treated products for which the uniformity of

spherical structure, mechanical properties and coating quality are

dramatically improved through our fully customized bell type furnace.

The products show excellent cold forging features and improvement of the

life span of metallic patterns.

Furthermore, our equipments show outstanding results for heat treatment

of both SAE1045 and Bearing Steels which are delicate in heat treatment.
