ASTM A790 / A789 Duplex Steel Pipe For Oil And Gas Industry
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 ) .

Usage of 2205 Duplex stainless steel should be limited to temperatures below 600° F . Extended elevated temperature exposure can embrittle 2205 stainless .
