Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of premium stainless steel products. Among their offerings are Stainless Steel 347 Fasteners, engineered for applications requiring high corrosion resistance, excellent high-temperature strength, and long-term reliability. These fasteners are ideal for industrial, chemical, and power-generation assemblies exposed to elevated temperatures and harsh corrosive environments. Each fastener is manufactured with precision and undergoes strict quality control to ensure consistent performance. Clients rely on 347 Fasteners for secure, durable, and dependable fastening solutions in demanding industrial, chemical, and high-temperature applications.
Stainless Steel 347 Fasteners are made from a titanium-stabilized austenitic stainless steel alloy containing approximately 17–19% chromium, 9–13% nickel, and low carbon content. Titanium stabilization prevents sensitization and enhances corrosion resistance during welding or high-temperature service. These fasteners typically exhibit tensile strength between 550–700 MPa and hardness around 180–220 HB. The austenitic structure provides excellent mechanical durability, creep resistance, and dimensional stability under thermal and mechanical stress. 347 Fasteners are suitable for industrial, chemical, and high-temperature applications requiring long-term reliability and corrosion resistance.
