Product Overview
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 superior corrosion resistance.
Temperature Limitations
This grade is not suitable for use above 300°C due to brittle micro-constituent precipitation, or below -50°C due to ductile-to-brittle transition.
Key Benefits
High resistance to pitting and crevice corrosion
Excellent performance in most caustic environments
Superior weldability characteristics
Higher corrosion resistance than most austenitic stainless steels
