Product description
ASTM A403 S31254, 254SMO Super Duplex Steel Elbow
ASTM A403 UNS S31254 Super Duplex Stainless Steel Pipe Fitting is a high-alloy austenitic stainless steel developed for use in seawater and other aggressive chloride-bearing media. 254SMO Super Duplex Steel Buttweld Pipe Fittings combine good mechanical strength and high ductility with excellent corrosion resistance in various environments. ASTM A403 UNS S31254 Buttweld Super Duplex Stainless Steel Pipe Fittings are also known as 254 SMO buttweld pipe fittings. These steel fittings have excellent corrosion resistance and combine good mechanical strength. The alloy is ductile and has excellent corrosion resistance in a wide range of environments. 6 Mo (UNS S31254) is a super austenitic stainless steel with a high level of molybdenum and nitrogen, having high resistance to pitting and crevice corrosion as well as high strength.
