Stainless Steel 409 is a ferritic stainless steel primarily made with chromium, usually around 10.5–11.75%, and has a low carbon content that boosts weldability and toughness. With minimal nickel content, it remains cost-effective while still providing decent corrosion resistance. In terms of mechanics, 409 stud bolts deliver good tensile strength, moderate yield strength, and excellent oxidation resistance at high temperatures. They also boast good formability and thermal stability, making them ideal for applications that experience cyclic heating and cooling in mildly corrosive environments.
