Liam Pipes & Tubes is a leading supplier of Stainless Steel 310H Seamless Tubing, designed for high-temperature, high-stress applications in Houston, USA. 310H, the high-carbon variant of 310, offers better creep strength and oxidation resistance at elevated temperatures. The seamless design provides uniformity, strength, and superior pressure containment, making it ideal for power generation, furnace systems, and petrochemical processes. Manufactured in line with ASTM A213 and ASME SA213 standards, our 310H tubing meets strict requirements for corrosion resistance, thermal stability, and dimensional accuracy. We offer cut-to-length, annealed, and pickled options tailored to your engineering needs.
310H seamless tubing includes 24–26% chromium, 19–22% nickel, and ~0.04–0.10% carbon to improve creep strength. It provides tensile strength of ~515 MPa, yield strength of ~205 MPa, and elongation of ~40%. This tubing maintains structural stability and resists oxidation up to 1100°C in continuous use. The seamless design removes weld seams, ensuring consistent wall integrity and pressure resistance. 310H is preferred in systems that experience extreme thermal gradients, pressure changes, and harsh conditions like sulfuric or carburizing gases. Its metallurgical makeup supports long-term performance in severe high-temperature industrial processes.

310H Seamless Tubing is commonly used in superheaters, waste heat boilers, furnace tubes, radiant coils, and refineries that operate above 800°C. It is ideal for pressure-bearing applications where seamless strength and high thermal resistance are critical. Uses include catalytic cracking systems, steam reformers, and heat exchanger bundles. This tubing also performs well in incinerators, cement kilns, and gas turbines, especially where scaling, carburization, and oxidation are concerns. In metallurgical and heat treatment facilities, it ensures structural integrity under continuous thermal cycling. Its strong creep resistance makes it essential for components under sustained mechanical and thermal stress.
