Renowned for its precision-engineered products and strict adherence to international standards, Ojas provides dependable tubing solutions for various industries, including heat treatment, petrochemical, power generation, and furnace manufacturing. Stainless Steel 309 is an austenitic alloy rich in chromium and nickel, offering exceptional oxidation resistance and thermal stability. With a strong commitment to performance, durability, and timely delivery, Ojas Pipes and Tubes has established itself as a reliable partner for advanced stainless steel tubing needs in global markets.
Stainless Steel 309 Tubing is composed of roughly 22–24% Chromium and 12–15% Nickel, along with trace amounts of Manganese, Silicon, Phosphorus, Sulfur, and a maximum carbon content of 0.20%. This unique blend boosts oxidation resistance and high-temperature strength. The alloy boasts a tensile strength of about 620 MPa, a yield strength of around 310 MPa, and an elongation of approximately 40%. With impressive creep resistance and excellent thermal stability, SS 309 tubing is perfect for extended exposure to high heat, making it an ideal choice for structural and pressure-bearing components in elevated temperature settings.
