Stainless Steel 409 Fasteners are made from ferritic stainless steel alloys that contain 10.5–11.7% chromium, low carbon, and small amounts of titanium for stabilization. This unique composition provides moderate corrosion resistance, especially against exhaust gases and atmospheric conditions, while also ensuring good oxidation resistance at higher temperatures. On the mechanical side, these fasteners offer reliable tensile strength, ductility, and toughness, along with fair creep resistance. While they may not be as corrosion-resistant as some higher grades, they excel in thermal stability, making them ideal for structural and automotive fastening applications in moderately corrosive and high-heat environments.
