Outokumpu has completed upgrades to the North American quarto plate facility in New Castle, Indiana, US. The upgrades represent an investment of more than EUR 45 million that will allow the mill to improve production efficiencies to better compete in the global stainless steel market. Outokumpu announced the investment plans in late 2007. The Indiana mill is the only Outokumpu location in North America producing specialised stainless steel plate recognized for its high resistance to corrosion. The upgrades include new equipment and equipment enhancements for process improvements. These equipment investments include a new plate finishing line with in-line annealing, shot blasting, and levelling as well as improvements to the 120in wide line including state-of-the-art environmental controls.
