Efficient integrated single-site operation
Located in northern Finland, Tornio Works is one of the largest stainless steel mills in the world and also the world's most integrated single-site operation. The main products are cold rolled and hot rolled 300-series austenitic stainless steel coils and sheets, ferritic grades are also part of the product portfolio. The integrated production process starts at the nearby Kemi chromite mine, continues in the Tornio ferrochrome smelter and proceeds through two stainless steel melt shops, a hot rolling mill and cold rolling lines. The majority of finishing operations are carried out in Terneuzen in the Netherlands.
Annual production capacities at Tornio Works are:
- 1.65 million tonnes of melting
- 1.6 million tonnes of hot rolling
- 1.2 million tonnes of finished products from the cold rolling mills
Majority of stainless steel produced in Tornio is standard austenitic stainless containing nickel in addition to chrome and iron. Outokumpu also produces 400-series ferritic stainless steel in Tornio. As ferritic grades do not contain nickel, prices for these products have traditionally been less volatile than those of the Group's main product, 300-series austenitic stainless steel. Outokumpu's production capacity in ferritic grades totals some 180 000 tonnes.
Some black hot band material from Tornio is also delivered to both internal and external customers.
Research and development activities carried out at the Tornio Research Centre focus on process, product and application development. Read more about R&D.
