Walid Stainless, based in Tunis, Tunisia, is a trusted manufacturer and supplier of premium stainless steel products. Among their offerings are Stainless Steel 348 Fasteners, designed for applications requiring excellent corrosion resistance, high-temperature strength, and long-term durability. These fasteners are ideal for industrial, chemical, and power-generation assemblies exposed to elevated temperatures and harsh environments. Each fastener is manufactured with precision and undergoes strict quality control to ensure consistent performance. Clients rely on 348 Fasteners for secure, durable, and dependable fastening solutions in demanding high-temperature and industrial applications.
Stainless Steel 348 Fasteners are made from a high-temperature austenitic stainless steel alloy containing approximately 17–19% chromium, 9–13% nickel, and small amounts of carbon and titanium. Titanium stabilization improves resistance to intergranular corrosion during welding and high-temperature service. These fasteners typically exhibit tensile strength between 600–750 MPa and hardness around 180–220 HB. The austenitic structure ensures excellent creep resistance, dimensional stability, and mechanical durability under elevated temperatures. 348 Fasteners are suitable for industrial, chemical, and high-temperature applications requiring long-term reliability and corrosion resistance.
