Material Properties & Characteristics
Duplex 2205 stainless steel (UNS S32205) is a nitrogen-enhanced alloy that provides superior corrosion resistance compared to standard austenitic stainless steels. This grade is not recommended for use above 300°C or below -50°C due to micro-constituent changes.
Key Benefits
High resistance to pitting and crevice corrosion
Excellent performance in caustic environments
Superior strength and durability
Good weldability and fabrication properties
