Stainless Steel 409 Stud Bolts consist of a ferritic stainless steel alloy with about 10.5–11.75% chromium and low carbon content (≤0.08%). Manufacturers often add titanium to improve weldability and decrease grain growth at high temperatures. SS 409 provides moderate tensile strength of about 380–620 MPa and yield strength of 170–300 MPa, depending on temper and heat treatment. It has good oxidation resistance and keeps its structural stability at high temperatures. Although it is less resistant to corrosion than austenitic grades, SS 409 balances strength, thermal resistance, and cost, making it perfect for applications where mechanical durability is prioritized over chemical resistance.
