Stainless Steel 409 Stud Bolts are primarily made up of chromium (10.5–11.75%), carbon (0.08% max), manganese, and silicon, featuring a low nickel content. This ferritic stainless steel grade is known for its good oxidation and corrosion resistance, especially in mild environments and automotive exhaust settings. The bolts boast a tensile strength of about 380–450 MPa and a yield strength of roughly 200–240 MPa. They offer excellent formability, weldability, and moderate mechanical strength, making them perfect for a variety of industrial and structural applications.
