Duplex 2205 is a nitrogen enhanced 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 structure of 2205 duplex stainless steel consists of austenite pools surrounded by a continuous ferrite phase . In the annealed condition , 2205 contains approximately 40 - 50 % ferrite . Often referred to as the work horse grade , 2205 is the most widely used grade in the duplex family of stainless steels .
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 .
