ASTM A928 UNS S32760 Stainless Steel Welded Pipe

ASTM A928 is the specification for electric fusion welded (EFW) austenitic and duplex stainless steel pipe suitable for corrosive or high-temperature applications. This pipe is produced by welding two steel plates together using an electric arc to form a single pipe. The welding process creates a strong, reliable joint capable of withstanding high pressures and temperatures.

Superduplex UNS S32760 EFW pipe is an austenitic-ferritic stainless steel with excellent resistance to pitting and crevice corrosion. Its chromium content is approximately 25% or greater. As the chromium content increases significantly, the alloy's corrosion resistance also increases. ASTM A790 UNS S32760 welded pipe offers greater resistance to pitting corrosion than conventional stainless steels and duplex alloys. Its high strength allows it to be used in high-pressure environments. Furthermore, due to its low coefficient of thermal expansion, Superduplex 32760 pipe can be used at high temperatures without deformation.
