Stainless Steel 310 and 310S Welded Pipes Manufacturer, Supplier and Exporter in Houston , USA

Liam Pipes & Tubes supplies Stainless Steel 310 and 310S Welded Pipes, made in Houston, USA, for corrosion–prone and high–temperature applications. SS 310 provides better oxidation resistance and strength, whereas SS 310S, having reduced carbon content, provides better weldability and decreased sensitization upon welding. These pipes are produced by advanced welding processes, ensuring strength, durability, and dimensional stability. Meeting the standards of ASTM A312 and A358, these pipes are best suited for components of industrial furnaces, flue gas systems, and heat exchangers. Their high performance under varying thermal and corrosive environments makes them a preferred option for high-duty piping systems.

SS 310/310S has 24–26% Cr, 19–22% Ni, and carbon composition of ≤0.25% for 310 and ≤0.08% for 310S. These pipes, upon welding, provide tensile strength of ~515 MPa, yield strength of ~205 MPa, and ~40% elongation. The reduced carbon in 310S enhances resistance to intergranular corrosion. Both grades have superb resistance to oxidation at 1100°C and maintain mechanical strength in thermal stress. The welded construction offers high structural integrity and is appropriate for low-pressure, non-critical heat and corrosive environment piping systems.

310/310S Welded Pipes are employed in petrochemical facilities, thermal process equipment, flue gas ductwork, and radiant tubes. They are well-suited for heat exchangers, kilns, burners, and incinerators. SS 310 offers excellent creep resistance in high-temperature equipment, whereas SS 310S is used in applications where welding and thermal cycling are frequent. These pipes also find application in sulphur–containing atmospheres, power generation equipment, and food processing machinery. The capability to handle high temperature and oxidizing environment makes them optimal for applications that need long-term thermal performance and corrosion resistance in less demanding pressure-bearing situations.
