Our ASTM A789, A790 Super Duplex Pipes and Tubes have larger contents of molybdenum, nickel, and chromium and mechanical properties of higher yield and tensile strength. Super Duplex 2507 ERW Pipes has improved corrosion resistance properties when compared to other duplex stainless steels.
Our UNS S32750 Pipes are widely used in oil refinery heat exchangers, cargo tanks and pressure vessels, seawater applications, desalination plants, refineries and petrochemical plants. Also, our UNS S32760 Pipes have the advantage of lower nickel content, making it an attractive option compared to austenitic grades, especially when the cost of nickel is high.
Meanwhile, WNR 1.4501 Tubing have much in common with austenitic and ferritic stainless steels, but these WNR 1.4410 Tubing have better resistance than most austenitic grades, more toughness than most ferritic grades and higher strength than most grades of either type. Our 2507 Super Duplex Seamless Pipes and Tubes are available in quite reasonable rates to our valuable customers.
