A358 GR 347H

Available in sizes ranging from 6 inches to 60 inches nominal bore (NB), these pipes can be customized with wall thicknesses in schedules such as SCH 10, SCH 40, SCH 80, and SCH XXS. They exhibit superior mechanical properties, including a tensile strength of 515 MPa and a minimum yield strength of 205 MPa, making them reliable under extreme conditions. The high carbon content enhances creep resistance, ensuring prolonged performance in high-pressure and high-temperature environments.

A358 GR 347H Stainless Steel Pipes are composed of 17-19% chromium, 9-13% nickel, and controlled carbon content (0.04-0.10%) with niobium stabilization. This unique composition offers excellent resistance to oxidation, scaling, and stress corrosion cracking. The pipes are available in various forms, including round, square, and rectangular, with options for plain, beveled, or threaded ends. Surface finishes such as polished, pickled, and passivated coatings are also offered to meet specific project requirements.

To ensure precision and compatibility with international standards, A358 GR 347H pipes maintain strict dimensional tolerances with an outside diameter variation of ±1% and a wall thickness tolerance of +12.5%/-10%. These pipes undergo rigorous testing, including ultrasonic, radiographic, and hydrostatic examinations, to guarantee the highest quality.
