253MA Stainless Steel Pipe

as well as Fittings, Flanges, Bar, Plate, Valves

253MA is an austenitic, chromium-nickel stainless steel with heat resistance and high strength. 253MA 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.
