Walid Stainless, based in Tunis, Tunisia, is a trusted manufacturer and supplier of premium stainless steel products. Among their specialized offerings are Stainless Steel 409 Bolts, designed for applications requiring corrosion resistance, moderate strength, and high-temperature stability. These bolts are ideal for automotive, industrial, and structural assemblies exposed to mildly corrosive or high-temperature environments. At Walid Stainless, each bolt is manufactured with precision and undergoes rigorous quality control to ensure consistent performance. Clients rely on 409 Bolts for durable, reliable fastening solutions that provide stability, safety, and longevity in demanding conditions.
Stainless Steel 409 Bolts are made from a ferritic stainless steel alloy containing approximately 11–12% chromium, with a small addition of titanium for stabilization. This composition provides excellent oxidation resistance, moderate corrosion resistance, and thermal stability. The titanium prevents sensitization, enhancing performance at elevated temperatures. These bolts offer tensile strength typically between 450–550 MPa and hardness around 160–200 HB. The ferritic structure ensures dimensional stability, wear resistance, and reliability under mechanical and thermal stress, making 409 Bolts suitable for fastening applications in automotive and industrial environments.
