A358 GR 348

These pipes are available in sizes ranging from 6 inches to 60 inches nominal bore (NB) with various wall thickness schedules such as SCH 10, SCH 40, SCH 80, and SCH XXS, ensuring compatibility with diverse industrial needs. The tensile strength of A358 GR 348 pipes is 515 MPa, and the minimum yield strength is 205 MPa, making them highly reliable under extreme conditions. Their stabilization with niobium and tantalum enhances their resistance to oxidation and stress corrosion cracking.

The material composition of A358 GR 348 Stainless Steel Pipes includes 17-19% chromium and 9-13% nickel, complemented by niobium/tantalum, which enhances their stability under thermal cycling. These pipes are offered in multiple forms, such as round, square, and rectangular, with end options including plain, beveled, and threaded finishes. Available surface treatments like polished, pickled, and passivated ensure superior corrosion resistance and aesthetic appeal.

Dimensional tolerances for A358 GR 348 pipes are precisely maintained, with an outside diameter variation of ±1% and wall thickness tolerances of +12.5%/-10%. These pipes are manufactured using advanced electric fusion welding (EFW) techniques, combined with heat treatments like annealing at 1010-1120°C to achieve maximum performance. Rigorous testing methods, such as ultrasonic, hydrostatic, and radiographic inspections, ensure compliance with international quality standards.
