Product description
ASTM A790 S32750 Super Duplex Stanless Steel Pipe
ASTM A790 UNS S32750 is a variation of Super Duplex Stainless Steel. It is a Super Duplex Stainless Steel Pipe developed for applications which demand high strength and corrosion resistance. S32507 has 25% chromium, 4% molybdenum, and 7% nickel. The high molybdenum, chromium and nitrogen content causes high resistance to chloride pitting and crevice corrosion attack and the duplex structure provides ASTM A790 UNS S32507 with exceptional resistance to chloride stress corrosion cracking(SCC). The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion.
