Super Duplex Steel Flanges ASTM A182 F53, UNS S32750 Weld Neck Flange, RF, FF, B16.5
Super Duplex Steel Flanges ASTM A182 F53, UNS S32750 Weld Neck Flange, RF, FF, B16.5
ASTM A182 F53(UNS S32750) Super Duplex Steel Flanges are made from a super duplex stainless steel which has 24% chromium, 3% molybdenum, 6% nickel and carbon and so on. ASTM A182 F53 Super Duplex Stainless Steel Weld Neck Flange is widely used for high temperature and high pressure applications. F53 has excellent resistance to pitting and crevice corrosion resistance. Thus ASTM A182 F53 super dplex stainless steel is used primarily in highly corrosive conditions.
