A358 GR 321

A358 GR 321 Stainless Steel Pipes are available in nominal bore (NB) sizes ranging from 6 inches to 60 inches, with customizable wall thicknesses adhering to SCH 10, SCH 40, SCH 80, and SCH XXS schedules. Titanium stabilization enhances their resistance to carbide precipitation, particularly in high-temperature applications up to 870°C. The material composition includes 17-19% chromium and 9-12% nickel, providing outstanding corrosion resistance and strength. Additionally, these pipes undergo stringent heat treatments such as annealing, ensuring their reliability in demanding operational conditions.

Dimensional tolerances for A358 GR 321 pipes are meticulously controlled, with an outside diameter variation of ±1% and wall thickness tolerance of +12.5%/-10%. They are available with various end finishes like plain, beveled, or threaded and surface treatments such as pickled, polished, or passivated. Their exceptional mechanical properties, including a tensile strength of 515 MPa and a minimum yield strength of 205 MPa, make them suitable for critical applications such as chemical processing, exhaust systems, and heat exchangers.
