SUPER DUPLEX STAINLESS STEEL FLANGE, A182 F53 UNS S32750 B16.5 FORGED FLANGE
UNS S32750 A182 F53 is a high alloy duplex stainless steel. F53 has excellent resistance to pitting and crevice corrosion resistance compared with the ordinary austenitic or duplex types. Due to this A182 F53 stainless steel is used primarily in highly corrosive conditions. UNS S32750 is a super duplex stainless steel supplied in the solution annealed condition. As a super duplex stainless steel, it combines the desirable aspects of both austenitic and ferritic grades. The higher chromium, molybdenum and nitrogen contents result in a Pitting Resistance Equivalent number (PREN) of >41, providing pitting and crevice corrosion resistance superior to austenitic and duplex stainless steels in almost all corrosive media, and a Critical Pitting Temperature exceeding 50°C.
