Liam Pipes and Tubes stands out as a top-notch manufacturer and supplier of Stainless Steel 321 Tubing right here in Houston, USA. We pride ourselves on delivering reliable and high-performance tubing solutions tailored for demanding industrial applications. Stainless Steel 321 is a titanium-stabilized austenitic stainless steel, celebrated for its remarkable resistance to intergranular corrosion and oxidation, particularly in high-temperature settings. At Liam Pipes and Tubes, we produce 321 tubing that adheres to strict international quality standards, ensuring our products boast exceptional durability, weldability, and thermal stability. This tubing finds its way into various industries, including aerospace, chemical processing, heat treatment, and power generation, where consistent performance under heat and stress is crucial.
Our Stainless Steel 321 Tubing is composed of Chromium (17–20%), Nickel (9–13%), Carbon (≤0.08%), and Titanium (≥5xC%) for stabilization, along with Manganese, Silicon, and other trace elements. The addition of titanium effectively prevents carbide precipitation during welding and heat exposure. In terms of mechanical properties, it offers a tensile strength of about 515 MPa, a yield strength of around 205 MPa, and an elongation of 35%. This tubing maintains its strength and corrosion resistance even when exposed to temperatures as high as 870°C (1600°F), making it perfect for high-heat, welded structures and process environments.

Stainless Steel 321 Tubing is a go-to choice for applications that demand high-temperature strength and resistance to intergranular corrosion. You’ll often find it in exhaust systems, heat exchangers, furnace components, and boiler tubes. It’s also widely used in chemical processing plants, refineries, aerospace systems, and thermal oxidizers. Thanks to its titanium stabilization, 321 tubing is particularly suited for welded structures that face prolonged high temperatures, as it resists sensitization and keeps its mechanical integrity intact. It’s the preferred material for industries that require durable, weldable, and thermally stable tubing solutions, especially under cyclic heating and oxidizing conditions.
