With its headquarters in Chennai, India, Vipul Pipes and Tubes is a top producer and supplier of stainless steel 309 pipes, providing dependable piping solutions designed for oxidising and high-temperature conditions. Austenitic chromium-nickel stainless steel SS 309 is renowned for its moderate resistance to corrosion and exceptional heat resistance. Vipul Pipes and Tubes is dedicated to providing top-notch products that satisfy global standards, catering to a variety of industries such as thermal processing, petrochemicals, power generation, and furnaces. The business has established a solid reputation in both domestic and foreign markets by emphasising quality, dependability, and prompt delivery.
Iron, 22–24% chromium, and 12–15% nickel make up the majority of stainless steel 309 pipes, with a maximum carbon content of 0.20%. Because of its composition, the alloy has exceptional resistance to scaling and oxidation at high temperatures. With a tensile strength of roughly 550 MPa, yield strength of 205 MPa, and elongation of 40%, SS 309 provides good mechanical strength. Even at cryogenic temperatures, its austenitic structure offers good toughness. Because of its high chromium and nickel content, SS 309 can withstand thermal cycling and high heat exposure without losing its structural integrity.
