Duplex Steel 2205

 

Duplex 2205 stainless steel, comprising both ferritic and austenitic structures, is widely utilized in applications that require exceptional corrosion resistance and strength. The S31803 grade has been improved to become UNS S32205, resulting in higher corrosion resistance. However, when exposed to temperatures exceeding 300°C, the micro-constituents of this grade may become brittle due to precipitation. Conversely, exposure to temperatures below -50°C could cause the micro-constituents to undergo a ductile-to-brittle transition. As a consequence, this particular stainless steel grade may not be suitable for use at extreme temperatures.
