A312 GR 310Hcb

The A312 GR 310Hcb pipes are available in sizes ranging from 1/8 inch to 24 inches nominal bore (NB) with wall thicknesses ranging from SCH 10 to SCH XXS. With high chromium (24-26%) and nickel (19-22%) content, along with the addition of niobium (columbium), these pipes deliver outstanding thermal stability and creep strength, making them ideal for prolonged exposure to high-temperature environments. They are available in both seamless and welded forms with customizable ends, including plain, beveled, or threaded options, and various surface finishes such as polished, pickled, and annealed.

These pipes are manufactured to conform to ASTM A312 specifications and undergo rigorous testing to ensure quality and reliability. With a tensile strength of 515 MPa and a yield strength of 205 MPa, A312 GR 310Hcb pipes are engineered to perform under extreme stress and thermal conditions. Their niobium content further enhances their resistance to thermal fatigue and creep deformation, making them suitable for critical applications in furnaces, chemical processing units, and industrial kilns.

Kwality Steelage Pvt. Ltd. adheres to stringent dimensional tolerances, with outside diameter variations within ±0.25 mm and wall thicknesses conforming to ASTM standards. These pipes are also available in custom lengths of up to 12 meters to cater to specific project requirements. The company ensures that all pipes undergo ultrasonic, radiographic, and hydrostatic testing to meet the highest quality standards.
