UNS S32750 / SAF2507/ 1.4410 F53 022Cr25Ni7Mo4N Super Duplex steel seamless pipe and tube
Material Summary
Stainless steel Super Duplex 2507 is designed to handle highly corrosive conditions and situations were high strength is required. High molybdenum, chromium and nitrogen content in Super Duplex 2507 help the material withstand pitting and crevice corrosion. The material is also resistant to chloride stress corrosion cracking, to erosion corrosion, to corrosion fatigue, to general corrosion in acids. This alloy has good weldability and very high mechanical strength.
