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.   Corrosion Resistance   2205  duplex stainless steel is a cost effective solution for many applications where  the 300 series stainless steels are susceptible to chloride stress corrosion  cracking. Stress corrosion cracking occurs when stainless steels are subjected  to tensile stress, while in contact with solutions containing chlorides. Increasing  temperatures also increase the susceptibility of stainless steels to stress  corrosion cracking. The  combination of chromium, molybdenum and nitrogen convey the good resistance of  2205 to chloride pitting and crevice corrosion. This resistance is extremely  important for services such as marine environments, brackish water, bleaching  operations, closed loop water systems and some food processing applications.  The high chromium, molybdenum and nitrogen contents of 2205 provide corrosion  resistance superior to common stainless steels, such as, 316L and 317L in most  environments     Chemical  Composition, %
