A358 GR 317L

A358 GR 317L Stainless Steel Pipes are available in sizes ranging from 6 inches to 60 inches nominal bore (NB), with wall thicknesses supporting various schedules, such as SCH 10, SCH 40, SCH 80, and SCH XXS. These pipes are crafted from premium-grade stainless steel containing 18-20% chromium, 11-15% nickel, and 3-4% molybdenum. The reduced carbon content of this grade prevents carbide precipitation during welding, ensuring optimal corrosion resistance, even in chloride-rich environments.

Dimensional tolerances for A358 GR 317L pipes are meticulously maintained, with an outside diameter tolerance of ±1% and wall thickness variation of +12.5%/-10%. These pipes are subjected to heat treatment processes such as annealing and stress-relieving to achieve superior mechanical stability. With a tensile strength of 485 MPa and a minimum yield strength of 170 MPa, these pipes deliver reliability and robustness under challenging operational conditions.

To cater to diverse industrial requirements, Kwality Steelage Pvt. Ltd. offers A358 GR 317L pipes with end finishes like plain, beveled, or threaded and surface options such as pickled, polished, or passivated. These pipes undergo rigorous testing, including ultrasonic, hydrostatic, and radiographic inspections, ensuring adherence to international quality standards. Backed by global certifications, our pipes serve clients across Europe, the Middle East, Southeast Asia, and beyond. Contact us today for tailored solutions and unmatched service.
