Custom ASTM A276/Uns S32750/ASTM A240 Stainless Steel Plate for Desalination Equipment Duplex Steel 2507 Sheet
ZHEJIANG ZHONGZHENG STAINLESS STEE MANUFACTURING CO., LTD is a special stainless steel manufacturer with 20 years of manufacturing experience.
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.
