Duplex Stainless Steel tubes - duplex stainless steel, duplex tubes, superduplex

Duplex UNS S31803/1.4462 is a duplex stainless steel with approximately 50% ferrite and 50% austenite. This grade has good mechanical strength at room temperature, resistant to corrosive attack, including pitting and is resistant to stress corrosion cracking. The grade is a successful alternative to the normal 300 series austenitic stainless steels, where its higher strength and resistance to stress corrosion cracking is required in critical applications. Please note that we have a minimum order value of £10,000.
