UNS S31254 Stainless Steel Plate

S31254 stainless steel plate (equivalent to UNS N08926, 1.4547) is a super austenitic stainless steel containing high molybdenum (more than 6%), high nitrogen and copper elements. It has extremely high resistance to pitting and crevice corrosion, and its PRE value can reach 42-44, far exceeding 316L and duplex steel. It is particularly suitable for strong corrosion environments such as seawater, salt water and chlorides.
