2205 Duplex Stainless Steel Characteristics
Duplex 2205 stainless steel combines both ferritic and austenitic properties, making it ideal for applications requiring excellent corrosion resistance and high strength. The S31803 grade has been refined into UNS S32205, offering enhanced corrosion resistance.
This grade undergoes precipitation of brittle micro-constituents above 300°C and ductile-to-brittle transition below -50°C, making it unsuitable for use at these extreme temperatures.
Key Benefits of Duplex 2205:
High resistance to pitting and crevice corrosion
Excellent performance in most caustic environments
Superior weldability characteristics
Higher corrosion resistance than most austenitic stainless steels
