Duplex 2205 stainless steel (UNS S32205) is nitrogen-enhanced for superior corrosion resistance and mechanical strength. This grade offers higher corrosion resistance than most austenitic stainless steels and is not recommended for use below -50°C or above 300°C.
Key Benefits:
High resistance to pitting and crevice corrosion
Excellent performance in most caustic environments
Good weldability and fabrication characteristics
