A358 GR 347LN

These pipes are available in a wide size range, from 6 inches to 60 inches nominal bore (NB), and can be customized with wall thicknesses in schedules such as SCH 10, SCH 40, SCH 80, and SCH XXS. With a tensile strength of 515 MPa and a minimum yield strength of 205 MPa, these pipes are engineered for demanding operational conditions. Nitrogen addition improves their mechanical properties, particularly their resistance to pitting and crevice corrosion.

The material composition of A358 GR 347LN Stainless Steel Pipes includes 17-19% chromium, 9-13% nickel, and nitrogen (0.10-0.30%), along with niobium stabilization. This unique combination enhances their oxidation resistance, toughness, and durability. The pipes are available in multiple forms, including round, square, and rectangular, with end options such as plain, beveled, or threaded. Surface finishes like polished, pickled, and passivated are provided to meet diverse project specifications.

Dimensional tolerances for A358 GR 347LN pipes are maintained with an outside diameter variation of ±1% and a wall thickness tolerance of +12.5%/-10%. These pipes undergo rigorous quality assurance processes, including ultrasonic, radiographic, and hydrostatic testing, ensuring compliance with international standards.
