    Stainless Steel 2205

     

    Duplex 2205, also known as UNS S32205, is a nitrogen-enhanced stainless steel. Users choose Duplex 2205 for its excellent corrosion resistance along with its high strength. It is important to note that Duplex 2205, offers much higher levels of corrosion resistance than most other austenitic stainless steels. Other benefits include:

    High resistance to pitting and crevice corrosion
    Excellent in most caustic environments
    Good weldability

    Performance Table

     

    To be considered Duplex 2205, a stainless steel must have a chemical composition that includes:
