A358 GR H347

These pipes are available in sizes ranging from 6 inches to 60 inches nominal bore (NB) with wall thicknesses adhering to various schedules, including SCH 10, SCH 40, SCH 80, and SCH XXS. With a tensile strength of 515 MPa and a minimum yield strength of 205 MPa, A358 GR H347 pipes are engineered to perform under extreme conditions. Their niobium stabilization prevents carbide precipitation, making them highly reliable for high-temperature welding and prolonged exposure to heat.

The material composition of A358 GR H347 pipes includes 17-19% chromium, 9-13% nickel, and a controlled carbon content of up to 0.10%, with the addition of niobium. These properties make the pipes highly resistant to corrosion, scaling, and thermal fatigue. The pipes are offered in various forms, including round, square, and rectangular, with options for plain, beveled, or threaded ends. Surface finishes like pickling, polishing, and passivation are also available to meet diverse project requirements.

Dimensional tolerances for A358 GR H347 pipes are strictly maintained, with an outside diameter variation of ±1% and a wall thickness tolerance of +12.5%/-10%. To ensure the highest quality, the pipes undergo rigorous testing, including ultrasonic, radiographic, and hydrostatic examinations.
