Jyoti Steels is a leading supplier and manufacturer of Super Duplex Steel Tubing S32750 in Mumbai, India. As a leading performer in high-strength stainless steel solutions, Jyoti Steels supplies tubes made of S32750-grade, which exhibits high strength as well as maximum corrosion resistance. The tubes are designed for applications in severe industry and are made according to global quality standards. With an emphasis on strength and accuracy, Jyoti Steels serves industries like oil & gas, petrochemical, marine, and power, providing consistent performance even in extreme conditions.
Super Duplex Steel Tubing S32750 has Chromium (24–26%), Nickel (6–8%), Molybdenum (3–5%), Nitrogen (~0.24–0.32%), and Iron as the remainder. Other elements are Manganese (<1.2%), Carbon (<0.03%), Copper (~0.5%), and Tungsten (~0.5%). The chemical composition achieves high resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Mechanically, it provides tensile strength of ~795–850 MPa, yield strength of ~550 MPa, and elongation of approximately 25%. With its density of 7.8 g/cm³ and the thermal conductivity of approximately 15 W/m·K, S32750 tubing functions well in high-temperature and pressure conditions.
