Liam Pipes and Tubes is a well-respected manufacturer and supplier of Stainless Steel 409 Tubing based in Houston, USA. We pride ourselves on providing cost-effective and durable tubing solutions that are perfect for high-temperature and mildly corrosive environments. Stainless Steel 409 is a titanium-stabilized ferritic stainless steel, primarily designed for automotive and industrial exhaust applications. At Liam Pipes and Tubes, we ensure that our 409 tubing meets strict industry standards, offering excellent weldability, thermal stability, and corrosion resistance. Our products are trusted across various industries, including automotive, power generation, and heating systems, where performance, longevity, and resistance to scaling from heat exposure are essential.
The composition of Stainless Steel 409 Tubing mainly includes Chromium (10.5–11.75%), with low Carbon (≤0.03%) and small amounts of Titanium for stabilization. It also contains Manganese, Silicon, and Iron as base elements. This blend provides good oxidation and corrosion resistance in non-aggressive environments. In terms of mechanical properties, it boasts a tensile strength of about 380 MPa, a yield strength of around 170 MPa, and an elongation of 20%. The titanium content is particularly beneficial as it helps prevent sensitization during welding, ensuring structural stability and durability even in moderate heat and corrosive conditions.
