Stainless Steel 409 Nuts are primarily composed of iron with 10.5–11.7% chromium and small additions of titanium for improved stability and oxidation resistance. They provide moderate corrosion resistance and good mechanical strength, with a tensile strength ranging from 380–450 MPa. These nuts exhibit good ductility, weldability, and resistance to thermal stress. While not as corrosion-resistant as higher-grade stainless steels, Stainless Steel 409 Nuts balance strength, heat resistance, and economy, making them suitable for automotive exhaust systems, machinery assemblies, and industrial applications that require reliable performance under moderate stress.
