Outokumpu Oy, Finland, introduces Ultra Alloy 825, a titanium-stabilized austenitic nickel-base alloy with added copper, designed primarily for process equipment in the chemical and oil and gas industries. It provides exceptional corrosion resistance against some acids, as well as under so-called “sour service” conditions, i.e., in environments containing hydrogen sulfide.
“Outokumpu stands out as the only major stainless steel company that can offer this nickel-base alloy in coils up to 1500 mm wide, both hot-rolled and cold-rolled,” says Sandra Arman, Product Manager, Ultra range at Outokumpu. “We are currently running qualification trials for quarto plate products, and we target taking commercial pilot orders soon to expand our offering even further.”
Ultra Alloy 825 fulfills the requirements of W.-Nr. 2.4858, UNS N08825, and ISO NW8825 in the relevant material standards. In addition to coil and sheet, Ultra Alloy 825 is also available as wire rod.
