ASTM A790 UNS S32003 Stainless Steel Tube Water and Wastewater Treatment
Specifications
ASTM A790 covers seamless and straight-seam welded ferritic/austenitic stainless steel pipe intended for general-purpose applications.
ASTM A790 UNS S32003 is a super duplex stainless steel seamless or welded pipe standard for general corrosive service, emphasizing stress corrosion cracking resistance. It features a balanced microstructure of austenite and ferrite with high alloying elements like chromium, molybdenum, and nitrogen, providing high strength and superior corrosion resistance compared to standard duplex stainless steels. This material is suitable for harsh environments, including those with high chloride concentrations, and is used in industries like petrochemical, chemical, and marine.
