SAF 2507 Duplex Stainless Steel alloy (UNS S32750) is a super-duplex stainless steel, a high-alloy duplex steel with a PRE value of min 42. The grade is characterized by very good chloride corrosion resistance, combined with very high mechanical strength.
SAF 2507 is particularly suited for use in aggressive environments such as warm chlorinated seawater and acidic, chloride containing media.
