Liam Pipes and Tubes stands out as a top-notch manufacturer and supplier of Stainless Steel 446 Tubing right in Houston, USA. We take pride in crafting high-quality, corrosion-resistant tubing that’s built to thrive in extreme environments. Stainless Steel 446 is a ferritic stainless steel celebrated for its remarkable resistance to oxidation and high-temperature corrosion. At Liam Pipes and Tubes, we ensure our 446 tubing meets strict industry standards, delivering outstanding durability and performance. You’ll find our tubing widely used in industries like power generation, petrochemical, and industrial heating, where materials need to endure long-term exposure to high temperatures and harsh conditions without losing their strength or integrity.
Our Stainless Steel 446 Tubing is primarily made up of Chromium (23–27%), with a low Carbon content (≤0.03%) and only trace amounts of Nickel, Manganese, Silicon, and other elements. This unique composition grants it excellent oxidation resistance and high-temperature strength. In terms of mechanical properties, it boasts a tensile strength of around 450 MPa, a yield strength of about 275 MPa, and an elongation of nearly 20%. Thanks to its ferritic structure, it also offers good thermal conductivity and resistance to thermal fatigue, making it perfect for continuous operation in high-temperature settings.
