Duplex Series Grade 2205 Hot Rolled Stainless Steel Seamless Pipe:

Duplex 2205 stainless steel (both ferritic and austenitic) is used extensively in applications that require good corrosion resistance and strength. The S31803 grade stainless steel has undergone a number of modifications resulting in UNS S32205 and was endorsed in the year 1996. This grade offers higher resistance to corrosion.

At temperatures above 300°C, the brittle micro-constituents of this grade undergo precipitation, and at temperatures below -50°C the micro-constituents undergo ductile-to-brittle transition; hence this grade of stainless steel is not suitable for use at these temperatures.

Its general capabilities include:

  • Excellent oxidation resistance

  • Outstanding performance in marine/seawater environments

  • Low thermal expansion coefficients

  • High heat conductivity
