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
