Outokumpu Tornio operations is Outokumpu’s biggest integrated plant and it is the only fully integrated stainless steel facility in the world.
Tornio stainless steel operations consist of two stainless steel melt shop lines, hot rolling mill, cold rolling plant, brushing and polishing as well as slitting and cut-to-length lines. Through Outokumpu Shipping Oy, Outokumpu operates the Röyttä Harbor (the Port of Tornio), enabling convenient transport of stainless steel coils to customers and a finishing line in Terneuzen in the Netherlands. A leader in innovation, Tornio is also home to one of Outokumpu’s three R&D centers. In addition to stainless steel facilities, Outokumpu operates ferrochrome works in Tornio and the nearby Kemi Mine.
Production at Tornio focuses primarily on Outokumpu Classic family products: Moda, Core and Supra. Most of the stainless steel produced in Tornio is austenitic and ferritic. Tornio products are shipped directly to customers or used as feedstock to cold rolling plants in Germany and Outokumpu service centers around the world.
Stainless steel production began in Tornio in 1976 with a production capacity of 50,000 tpa (tonne per annum). A production expansion project completed in 2004 drove steel production capacity to 1.2 million tpa.
