A358 GR 316L

A358 GR 316L Stainless Steel Pipes are distinguished by their low carbon content, which minimizes the risk of carbide precipitation during welding, making them ideal for critical applications requiring superior intergranular corrosion resistance. These pipes are available in sizes ranging from 6 inches to 60 inches nominal bore (NB) with various schedules such as SCH 10, SCH 40, SCH 80, and SCH XXS, catering to diverse operational needs. The material composition features 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, enhancing their resistance to chloride-induced pitting and crevice corrosion.

Dimensional accuracy is maintained with an outside diameter tolerance of ±1% and wall thickness tolerances of +12.5%/-10%. These pipes are available with plain, beveled, or threaded ends and surface finishes including polished, pickled, and passivated, offering versatility for various applications. With a tensile strength of 485 MPa and a yield strength of 170 MPa minimum, A358 GR 316L pipes deliver reliable performance in demanding conditions.

Manufactured under strict quality control measures, these pipes undergo comprehensive testing, including ultrasonic, hydrostatic, and radiographic inspections, ensuring compliance with international standards.
