ASTM A790 / ASME SA790 S32750 Duplex Steel Pipe
Overview
ASTM A790 S32750 is a standard specification for seamless and welded ferritic/austenitic stainless steel pipe. S32750 is a super duplex stainless steel, which has a higher strength and better corrosion resistance than duplex stainless steels like S31803. This specification covers pipes that are intended for general corrosive service, high-temperature service, and low-temperature service. The pipes may be either seamless or welded and may be produced by various welding processes such as electric resistance welding, electric fusion welding, or submerged arc welding.
