PE ASTM A790 Stainless Duplex Steel Pipe Seamless 6000MM

Duplex Steel Pipe:

Duplex stainless steel was developed to combat common corrosion problems encountered with the 300 series stainless steels. “ Duplex ” describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless. The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy ( stress corrosion cracking resistance and high strength ) with those of an austenitic alloy ( ease of fabrication and corrosion resistance ).
