At Nascent Pipe & Tubes, we specialize in offering high-grade Stainless Steel 309 Pipes, meticulously engineered to meet the rigorous demands of high-temperature and corrosive industrial environments. These pipes are manufactured using superior quality raw materials and are compliant with international standards such as ASTM A312, ASTM A213, and ASTM A269. The UNS number for this alloy is UNS S30900, which corresponds to an austenitic stainless steel alloy designed for heat-resisting and oxidation-resisting applications.
Stainless Steel 309 is widely recognized for its high chromium and nickel content, which offers excellent corrosion resistance even in severe atmospheres involving sulfur and oxidizing gases. At elevated temperatures, SS 309 pipes provide outstanding scaling resistance and mechanical strength, making them ideal for industries such as petrochemical, refineries, power plants, heat exchangers, and boilers. These SS 309 seamless pipes and SS 309 welded pipes are ideal for fabrication operations, including forming and welding, without compromising the strength and corrosion-resisting properties.
