Stainless Steel 409 Stud Bolts are crafted from a ferritic stainless steel alloy, with chromium as the primary element, along with small amounts of carbon, nickel, and titanium for stabilization. This blend provides moderate corrosion resistance and outstanding oxidation resistance at high temperatures. In terms of mechanics, SS 409 stud bolts deliver good tensile strength, stable hardness, and dependable performance under thermal stress. While they may not match the corrosion resistance of austenitic grades, their combination of strength, thermal stability, and affordability makes them perfect for exhaust systems and applications that face continuous heat exposure.
