ASTM A790 UNS S32808 Stainless Steel Tube For Chemical and Process Industry
Specifications
ASTM A790 covers seamless and straight-seam welded ferritic/austenitic stainless steel pipe intended for general-purpose applications.
ASTM A790 UNS S32808 is a duplex stainless steel pipe that combines high strength with excellent corrosion resistance, particularly to stress corrosion cracking in chloride and acidic environments. It is suitable for general corrosive service and is manufactured using seamless or straight-seam welded processes without filler metal. The UNS designation specifies its unique composition, and ASTM A790 defines the material's properties and testing requirements.
