Duplex 2205 is nitrogen reinforced stainless steel. Specially designed for use in highly corrosive environments where
the use of conventional stainless steel is impractical. UNS S32205 is an improved version of S31803 stainless steel
that provides a higher corrosion resistance class.

The content of chromium, molybdenum and nitrogen in the chemical composition of 2205 steel provides super 2205
with excellent resistance to chloride pitting and crevice corrosion. In this regard, 2205 steel is the best alternative to
316L and 317L steels for high humidity conditions.

Due to its excellent mechanical properties, Duplex 2205 excels in premature failure and sea water service. Also, 2205
steel is resistant to chloride cracking at 150℃.
It should be noted that the use of duplex 2205 steel is not recommended at temperatures above +316℃ and below -50℃.
Super duplex 2205 is characterized by high mechanical strength, energy absorption and low thermal expansion.
