ASTM A790 A789 S31803 1.4462 S32750 1.4410 (Super) Duplex Stainless Steel Pipe

ASTM A790 UNS S31803, UNS S32750 and UNS S32760 are duplex steel grades, which have high chromium and molybdenum elements, ASTM A790 UNS S31803 is the most widely used duplex stainless and it has excellent corrosion resistance, and high strength feature. Generally UNS S31803 Duplex stainless steel pipe is applied in corrosion and high-temperature environment. ASTM A790 UNS S32750 and ASTM A790 UNS S32760 are super duplex steel grades. ASTM A790 UNS S32750 Super Duplex Steel Pipe is an austenitic-ferritic stainless steel. It has excellent resistance to pitting and crevice corrosion. In chemical composition, the higher chromium and molybdenum content will ensure high tensile strengths and exhibits high thermal conductivity and low thermal expansion.
