ASTM A790 Pipe,S32205/S32750 Duplex Steel Pipe, Annealed & Pickled Surface

Duplex Steel Pipe：

  Duplex stainless steel that 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 ) .
