PRODUCT DESCRIPTION
UNS S32750(Duplex 2507) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel. Duplex 2507 is designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment.
UNS S32760 is a super duplex stainless steel with a microstructure of 50% austenite and 50% ferrite. UNS S32760 is designed for service in aggressive chloride-containing environments and has additions of W and Cu compared to UNS S32750. It has very good resistance to localized corrosion and stress corrosion cracking in combination with high mechanical strength.
HT PIPE supplys the ASME SA789 Seamless and Welded Tubes and ASME SA790 S31803 Seamless and Welded super Duplex Stainless Steel Pipe for the Oil and Gas, Refinery, Petrochemical and Power Industries.
