Stainless Steel 409 Stud Bolts are mainly made up of iron, chromium (10.5–11.75%), along with small amounts of carbon, manganese, silicon, and nickel. The addition of titanium helps stabilize the structure, enhancing both weldability and corrosion resistance. These bolts offer moderate mechanical strength, good oxidation resistance, and impressive performance at elevated temperatures. With a tensile strength ranging from about 380–450 MPa and decent ductility, Stainless Steel 409 Stud Bolts ensure durability and reliability in both oxidizing and mildly corrosive environments, promising a long service life in industrial and automotive applications.
