Stainless Steel 409 is a ferritic alloy that mainly consists of around 11–12% chromium, with a touch of titanium added to enhance stability and prevent grain growth. This alloy boasts impressive resistance to oxidation and corrosion, especially at elevated temperatures. The mechanical properties of Stainless Steel 409 bolts typically feature tensile strengths ranging from 450 to 600 MPa and yield strengths between 275 and 400 MPa, depending on the heat treatment process. Its low carbon content ensures excellent weldability and formability, making it a perfect fit for automotive and industrial fasteners.
