Acciaierie Valbruna has come a verylong way since its founding in 1925as a small company specialising in

forged equipment for use in agriculture, andafter experiencing total devastation from al-lied bombing during the second world war.Following a rebuild and enlargement of thecompany’s works in the immediate postwarperiod, at the end of the 1950s there was afocusing of the company away from the pro-duction of specialty low alloyed steels tothe production of high alloy steels, stain-less steels, high speed steels and special-ty alloys.Today, thanks to a strong commitment tocontinuous improvement in efficiency through

Acciaierie Valbruna is a private company with 2,500 employees and an annual output ofapproximately 200,000 tonnes of specialty steels. The company is a fully-integrated pro-ducer of stainless steel, high nickel and titanium alloy long products with mills in Vicen-za and Bolzano in Italy, as well as in Fort Wayne in the USA. Its products meet thehighest technical requirements for the most demanding of applications, and it has anextensive global distribution network ensuring constant direct contact with customerswherever they may be located around the world.

optimization of the production cycle, in-vestments in automation, research and de-velopment of new products, and expansionof the distribution network, Valbruna’s pro-duction is utilized in varied industrial sec-

tors such as food and pharmaceutical, aero-space, automotive, chemical and petro-chemical industries, construction, energy,mechanical, medical, naval, and manyothers.

supplies a range of ferritic, martensitic, aus-tenitic, PH and duplex stainless steel, aswell as nickel and silicon iron alloys for fuelinjection systems, engine valves, fasteners,exhaust and brake systems, and other com-ponents and structural parts.Specifically for fuel injection systems, Val-bruna produces high quality steels used forthe manufacture of safety components incontact with the propellant of the engine (beit petrol, diesel, LPG or other) that mustcomply with the high standards that onlycutting edge processes can satisfy. Thus,the important and continued investments inrecent years allow Valbruna to satisfy themost stringent requirements for many ran-ges of product, as for example in the field ofnon-destructive testing where it is able toguarantee the control of 100% of the crosssection of the bar by ultrasonic testing.

For Marine applications, where corrosiveenvironments are always present, Marinox®

and Aquashaft® identify a series of austen-itic, PH and duplex stainless steels inten-ded for the manufacture of propeller shaftsin the shipbuilding industry.

By using these types of steel, the designercan reduce the shaft dimensions and there-fore use smaller supports and seals. Thesimultaneous reduction of weight and hy-drodynamic resistance permits better per-formance and greater efficiency.

For the Building sector, Valbruna offers a

that is available in a range of stainless steelgrades including austenitic, superausteniticand duplex.

The benefits of using Reval in roads, brid-ges and buildings, Valbruna says, include:

� excellent corrosion resistance to chlorides� more than 100 years expected service

life in concrete� higher strength levels� better self healing when subjected to

damage and abrasion compared togalvanized or epoxy coated steel

� low life cycle cost� high ductility� longer storage and service life� better resistance to localized corrosion

mechanisms� low magnetic permeability� better fire and heat resistance com-

pared to black bar� resistance to seismic loading� easy use with carbon steel by lapping or

coupling

For Aerospace applications, like aeronauti-cal engines, structural components, fasten-ers & rivets, fittings & sensors and manyothers, Valbruna offers a range of highlyspecialised Aeroval® grades, able to offer thegreatest performance in environments sub-ject to great fluctuations of temperature andextended cycle fatigue while guaranteeing

absolute reliability,operational safetyand efficiency.

In Chemical and Petrochemical plants, theconditions of the use of steel are particular-ly critical due to the aggressiveness of trea-ted fluids and elevated temperatures at whichthey operate.

For this reason, many grades of stainlesssteel and nickel alloys produced by Valbru-na, are used in these sectors due to theirunique combination of high strength andexcellent resistance to corrosion in chlor-

alternative energy, such as solar, wind andgeothermic.Valbruna produces several products in dif-ferent grades of stainless steel, nickel andtitanium alloys that find applications in tur-bine hardware as well as turbine blading andvanes for the power generation market, andfrom the system and circuits subjugated to

The Maxival® rangeof stainless steelgrades, which hasbeen produced byAcciaierie Valbrunasince the early1980s, and whichhas been constant-ly improved, offersmachine shops amaterial grade which

has the same corrosion resistance andmechanical properties as standard stainlesssteel grades but with enhanced machinabil-ity. For the customer this means higher feedspeeds, longer tool life, less machine down-

time and fewer rejections. It is availableacross the grade range 304/304L, 304Cu,321, 316/316L, 303, 420, 329 (EN 1.4460),etc, but can be supplied in other grades onrequest.

Valbruna’s ferritic Magival® series is dedi-cated to solenoid technology applicationsproviding improved machinability and out-standing magnetic properties (high permea-bility and low coercive force).The carefully controlled chemical analysisand sophisticated working processes cre-ate a ferritic structure which is highly sensi-tive to variations in a magnetic field. Thisavoids the need for expensive heat treatmentby the user after machining. Due to theirextreme ease of magnetization and demag-netization, Magival grades are ideally sui-ted for use in the manufacture of magneticcores, solenoid valves, electromagnetic de-vices, flow regulators, injector componentsetc.

Valbruna also offers a range of Silicon-Ironalloys that are generally used in applications

magnetic stainless steels such as the Ma-gival series.

Valbruna’s quality systems - the companyis certified to ISO 9001, AS 9100 and ISO/TS 16949 - coupled with its philosophy andexpertise throughout the whole productionchain mean that the company can guaran-tee that its products are of the highest qual-ity and able to meet the increasing demandsof the high tech markets with improved per-formance, reliability and machining consist-ency.

Valbruna has always been committed torespecting environmental guidelines and thehealth and safety rights of employees: theVicenza and Bolzano plants are certified toISO 14001.

The company has an extensive and strate-gic distribution network which is its corner-stone in a global market, providing not onlya commercial presence around the world,but also ensuring continuous feedback fromcustomers. It has locations throughout Italyand the rest of Europe, as well as in Cana-da, the USA, Mexico, Hong Kong, Austra-lia, Malaysia, the UAE, India and South Af-rica.
