One of the other types of Duplex stainless steels is the Super Duplex stainless steel, with larger contents of molybdenum, nickel, and chromium and mechanical properties of higher yield and tensile strength. As a result super duplex or 2507 grade stainless steel has improved corrosion resistance properties when compared to other duplex stainless steels.
Super duplex stainless steel grade 2507 or S32760 exhibits better pitting and crevice corrosion resistance, with its PRE being greater than 40 compared to around 35 for Duplex grade 2205, 24 for 316L and 33 for 904L.
Super duplex pipes and tubes , Super Duplex plates are widely used in oil refinery heat exchangers, cargo tanks and pressure vessels, seawater applications, desalination plants, refineries and petrochemical plants.
Super duplex stainless steel have much in common with austenitic and ferritic stainless steels, but they have better resistance than most austenitic grades, more toughness than most ferritic grades and higher strength than most grades of either type. Duplex stainless steels also have the advantage of lower nickel content, making it an attractive option compared to austenitic grades, especially when the cost of nickel is high.
