Stainless Steel 409 is a ferritic chromium alloy that mainly consists of about 11–12% chromium, along with a touch of titanium to boost stability. This unique blend gives it impressive resistance to oxidation and corrosion, especially in high-temperature settings. The mechanical properties of SS 409 feature tensile strength ranging from 450 to 600 MPa and yield strength between 275 and 400 MPa, which can vary depending on how it’s processed. Its low carbon content guarantees excellent weldability and formability, making it a great fit for automotive exhaust systems and other industrial applications.
