S32750 Duplex Steel Seamless Pipe

Description

S32750 Duplex Steel Seamless Pipe

Pipe Profile  

S25073 duplex stainless steel tube is a ferritic-austenitic (duplex) stainless steel that combines the most beneficial properties of many ferritic and austenitic steels due to the high chromium and molybdenum content of the steel. Therefore, it has excellent resistance to pitting corrosion, crevice corrosion and uniform corrosion. The two-way microstructure ensures that the steel has high resistance to stress corrosion cracking and high mechanical strength.
