ASTM A790 UNS S32750 Stainless Steel Tube Heat Exchanger Tubes
Specifications
ASTM A790 covers seamless and straight-seam welded ferritic/austenitic stainless steel pipe intended for general-purpose applications.
ASTM A790 UNS S32750(Duplex 2507) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel, it can be the Seamless and Welded Ferritic/Austenitic Stainless Steel Pipe. This high molybdenum, chromium and nitrogen content results in excellent resistance to chloride pitting and crevice corrosion attack and the duplex structure provides 2507 with exceptional resistance to chloride stress corrosion cracking.
