SS 316 tubing is high-performance austenitic stainless steel tube with superior corrosion resistance and strength in harsh environments. Produced and supplied by Vinit Stainless in Chennai, India, these tubes are best suited for critical processes with exposure to chemicals, seawater, and acid media. SS 316 tubing finds extensive applications in chemical processing, food and beverage, pharmaceutical, and marine engineering industries. With a smooth interior surface, higher strength, and weldability, Vinit Stainless supplies SS 316 tubing in a range of sizes and finishes to international standard as well as customer-specific requirements for structural and high-purity applications.
SS 316 tubing consists of 16–18% Chromium, 10–14% Nickel, and 2–3% Molybdenum, with a carbon limit up to 0.08%. The molybdenum enhances resistance to crevice corrosion and pitting in environments containing chloride. These tubes possess a tensile strength of approximately 515 MPa and a yield strength of 205 MPa, with excellent elongation and hardness. SS 316 exhibits excellent strength at high temperatures and also toughness at sub-zero temperatures. It possesses great formability, weldability, and corrosion resistance, and thus is well suited for applications in aggressive or hygienic conditions.
