Alloy 2507, with UNS number S32750, is a famous super duplex stainless steel. As a member of the duplex stainless steel family, it is a two-phase alloy based on the iron-chromium-nickel system with a mixed structure of about equal proportions of austenite and ferrite. Due to the duplex phase balance, Alloy 2507 exhibits excellent resistance to general corrosion like that of austenitic stainless steels with similar alloying elements. Besides, it possesses higher tensile and yield strengths as well as significantly better chloride SCC resistance than its austenitic counterparts while maintaining better impact toughness than the ferritic counterparts.
