Liam Pipes & Tubes provides excellent quality Stainless Steel 304H ERW Pipes that are appropriate for high-pressure, high-temperature service, made in Houston, USA. SS 304H is a carbon–rich variant of 304, with enhanced strength and creep properties at high temperatures. Our ERW pipes are manufactured using cutting-edge welding technology, with precision and reliability being present in structural and process piping lines. Adhering to ASTM A312 specifications, our pipes are extensively utilized in power plants, refineries, and heat exchanger systems. Their weldability, thermal resistance, and cost-effectiveness make them a perfect fit for general industrial applications in moderately corrosive and thermal conditions.
SS 304H contains ~18–20% Cr, 8–11% Ni, and 0.04–0.10% C to enhance high-temperature strength. It provides tensile strength of ~585 MPa, yield strength ~240 MPa, and elongation of ~40%. These pipes retain strength in service temperatures up to 800°C. ERW fabrication produces clean weld seams and consistent wall thickness, appropriate for non-critical structural and pressure applications. 304H resists mild corrosion and oxidation in mildly acidic conditions. Its high carbon content contributes to improved creep resistance and is thus a good fit for heat exchangers, piping supports, and high-temperature industrial lines.

304H ERW Pipes are applied in boiler tubes, power generation piping, refinery units, and heat transfer systems that need long-term thermal exposure. They‘re appropriate for superheaters, pre-heaters, and pressure piping in high-temperature settings. These pipes are also prevalent in petrochemical plants, cement factories, and processing industries where oxidizing conditions are present. With their good weldability, they‘re perfect for welded assemblies in ductwork and heat-exposed structural supports. Their cost-effectiveness, thermal efficiency, and strength make them a perfect substitute for higher-cost high-alloy pipes in moderately stressed thermal and corrosive environments.
