A312 GR 310H pipes are available in both seamless and welded forms, with sizes ranging from 1/8 inch to 24 inches nominal bore (NB) and wall thickness options from SCH 10 to SCH XXS. Known for their tensile strength of 515 MPa and a minimum yield strength of 205 MPa, these pipes perform reliably under high-stress conditions. Their high chromium (24-26%) and nickel (19-22%) content provides excellent resistance to corrosion and scaling at elevated temperatures, up to 1100°C.

These pipes are fabricated with precision to maintain tight dimensional tolerances, ensuring compatibility with a wide range of industrial systems. Manufactured according to ASTM standards, they undergo rigorous heat treatments, including annealing and solution treatment, to meet the highest quality standards. With customizable options such as plain, beveled, or threaded ends and surface finishes like polished, pickled, or annealed, A312 GR 310H pipes cater to diverse project needs.

The chemical composition of A312 GR 310H Stainless Steel Pipes includes higher carbon content compared to standard 310 grades, which enhances their creep resistance and thermal conductivity. This makes them ideal for use in furnaces, kilns, and chemical processing equipment. To ensure reliability and durability, these pipes are subjected to extensive testing, including ultrasonic, hydrostatic, and radiographic examinations, to ensure compliance with industry standards.

Kwality Steelage Pvt. Ltd. ensures that these pipes are meticulously packed in wooden crates or bundles to prevent damage during transit. With a proven track record of serving clients globally, including the Middle East, Europe, and Southeast Asia, the company is committed to delivering superior quality and unparalleled customer service.

Welding and Heat Treatment for A312 GR 310H Pipes

A312 GR 310H Stainless Steel Pipes are heat-treated through annealing at temperatures between 1040°C and 1100°C to enhance corrosion resistance and mechanical strength. The higher carbon content improves the thermal stability of these pipes, making them suitable for extreme conditions. Post-weld heat treatment (PWHT) is generally not required due to the grade’s inherent resistance to thermal stress, but it can be applied for critical applications to ensure enhanced durability.
