One of the 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 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.
Stainless Steel 2507 Super Duplex pipes and tubes are available in both seamless and welded form in OD and NB sizes. In addition to standard sizes, which are available in stock, our specialty is to supply custom size SS Super Duplex cold drawn seamless tubes from our factory.
Stainless Steel 2507 Super Duplex pipes and tubes can be offered in random lengths of up to 6meters long or cut to a specific length as ordered. We also offer a complete range of stainless steel Super Duplex butt weld fittings including Super Duplex elbow, Super Duplex bends, Super Duplex tees, Super Duplex reducers and caps.
Seamless Super Duplex Pipes / Tubes: ASTM A 789 / 790, ASME SA 789 / 790
Welded Super Duplex Pipes / Tubes: ASTM A 789 / 790, ASME SA 789 / 790
Super Duplex Pipe Fittings & Flanges: ASTM A 815, ASME SA 815, ASTM A182 Grade F55
When compared to 2205 grade duplex stainless steel, 904L has similar corrosion resistant properties but lower mechanical strength. 2205 is also a lower cost option compared to 904L, but is not suitable for temperatures above 300°C. Grade 2205 is not generally suitable for use at temperatures above 300°C as it suffers from precipitation of brittle micro-constituents, nor below -50°C because of its ductile-to-brittle-transition.
