Walid Stainless, headquartered in Tunis, Tunisia, is a leading manufacturer and supplier of premium stainless steel products. Among their offerings are Stainless Steel 309 Fasteners, engineered for applications requiring exceptional high-temperature strength, oxidation resistance, and durability. These fasteners are ideal for furnaces, boilers, heat exchangers, and industrial equipment operating under extreme thermal conditions. Each fastener is manufactured with precision and undergoes rigorous quality control to ensure consistent performance. Clients rely on 309 Fasteners from Walid Stainless for secure, reliable, and long-lasting fastening solutions in demanding high-temperature and industrial applications.
Stainless Steel 309 Fasteners are made from a high-chromium, high-nickel austenitic stainless steel alloy containing approximately 23% chromium and 13% nickel, with low carbon content to prevent carbide precipitation. This composition provides excellent oxidation and corrosion resistance, along with high tensile strength at elevated temperatures. These fasteners typically exhibit tensile strength between 550–700 MPa and hardness around 170–210 HB. The austenitic structure ensures mechanical durability, thermal stability, and dimensional reliability under stress. 309 Fasteners are suitable for high-temperature industrial applications requiring long-term performance and durability.
