Stainless Steel 309/309S Pipes

Reliable 309 Stainless Steel Pipes Supplier from India, Get fast delivery on ASTM A312 TP309 Stainless Steel Pipe

Stainless Steel 309 and 309S pipes are high-temperature austenitic stainless steels made for strength and oxidation resistance. These grades contain chromium, nickel, carbon, silicon, manganese and other key elements that give them solid mechanical properties. They offer a minimum tensile strength of 515 MPa, a yield strength of 205 MPa, and a maximum hardness of 217 HB. The 309S version has lower carbon for better weldability and reduced carbide precipitation. Preston Pipes & Alloys is a trusted Stainless Steel 309S Pipe supplier offering reliable products made to exact standards and built for demanding use.

These pipes handle heat and corrosion well, making them ideal for high-temperature service. 309 stainless steel pipe resists oxidation in sulfur-rich settings up to 1832°F (1000°C). Common uses include heat exchangers, kilns, refineries, power plants, and thermal processing equipment. They're strong yet easy to weld, machine and form. ASTM A312 TP309 seamless pipe is known for clean finish, toughness, and strength under pressure. Stainless Steel 309S Pipe also works in marine and chemical areas due to its corrosion resistance and solid structure.
