Stainless Steel Super Duplex A815 UNS S32750 Tee / Elbow Butt Weld Fitting
Stainless Steel Super Duplex A815 UNS S32750 Tee / Elbow Butt Weld Fitting
conditions and situations were high strength is required. High molybdenum, chromium and nitrogen content inSuper Duplex 2507 help the material withstand pitting and crevice corrosion. The material is also resistantto chloride stress corrosion cracking,to erosion corrosion,to corrosion fatigue,to general corrosion inacids. This alloy has good weldability and very high mechanical strength.
Super Duplex UNS S32750 Pipe Fittings is widely used in Power,Marine,Chemical,Pulp and paper,Petrochemical,Water desalinization,0il and gas production.
