Introducing Andre Stainless, a top-notch manufacturer and supplier of Stainless Steel 409 Pipes right here in Singapore, Pulau Ujong. We specialize in providing durable and budget-friendly piping solutions for both automotive and industrial needs. SS 409 is a ferritic stainless steel celebrated for its outstanding oxidation resistance, particularly in high-temperature settings like exhaust systems. At Andre Stainless, we offer both seamless and welded 409 pipes in a variety of sizes and wall thicknesses, all crafted to meet ASTM A312 and other international standards. These pipes are designed to perform reliably in moderately corrosive and thermal environments, making them perfect for automotive exhausts, HVAC systems, and components in industrial furnaces.
When it comes to composition and mechanical properties, Stainless Steel 409 Pipes generally contain 10.5–11.75% chromium, with a low carbon content (≤0.08%) and a touch of titanium to help stabilize the microstructure. This alloy boasts moderate tensile strength ranging from 450–600 MPa and a yield strength close to 275 MPa. SS 409 is magnetic and provides excellent resistance to oxidation and scaling at temperatures reaching up to 900°C. While it may not resist corrosion as well as austenitic grades, it shines in mildly corrosive and high-temperature environments, especially where thermal stability and cost-effectiveness are key.
