253 MA Stainless Steel

Pipe, Bar, Plate, Fittings, Flanges, Valves

Applied Alloys International is Australia’s premier source of 253 MA / UNS S30815 Stainless Steel.

253 MA is an austenitic, chromium-nickel stainless steel with heat resistance and high strength. 253 MA stainless steel is alloyed with nitrogen and reactive elements suitable for a wide range of high-temperature applications. The use of rare earth metals in combination with silicon gives superior oxidation resistance up to 1150°C.
