A358 GR 317 Stainless Steel Pipes are available in nominal bore (NB) sizes ranging from 6 inches to 60 inches, with schedules such as SCH 10, SCH 40, SCH 80, and SCH XXS. These pipes are fabricated with a robust composition of 18-20% chromium, 11-15% nickel, and 3-4% molybdenum, offering exceptional resistance to chlorides and acidic environments. The inclusion of molybdenum enhances strength, durability, and resistance to localized corrosion. These features make A358 GR 317 pipes an ideal choice for applications requiring superior performance in harsh conditions.

Manufactured under strict quality controls, these pipes ensure precise dimensional tolerances, with an outside diameter (OD) variation of ±1% and wall thickness tolerances of +12.5%/-10%. Their exceptional mechanical properties, including a tensile strength of 515 MPa and a yield strength of 205 MPa, make them a reliable choice for fluid transport, structural applications, and heat exchangers. They are available with surface finishes like pickled, polished, and passivated, ensuring longevity and aesthetic appeal.

To meet diverse industrial needs, Kwality Steelage Pvt. Ltd. provides A358 GR 317 Stainless Steel Pipes in custom lengths up to 12 meters and end types such as plain, beveled, or threaded. Each pipe undergoes rigorous testing, including hydrostatic, radiographic, and ultrasonic inspections, ensuring adherence to international quality standards.

Welding and Heat Treatment for A358 GR 317 Pipes

A358 GR 317 Stainless Steel Pipes are designed to provide superior weldability and performance under high-pressure environments. Heat treatment processes, such as annealing, normalize the material structure and improve corrosion resistance. These pipes are particularly suited for environments with chlorides or reducing agents, as the molybdenum content minimizes pitting and crevice corrosion risks. Post-weld heat treatment (PWHT) is recommended for critical applications.
