Walid Stainless, headquartered in Tunis, Tunisia, is a leading manufacturer and supplier of premium stainless steel products. Among their offerings are Stainless Steel 347 Bolts, designed for applications requiring high corrosion resistance, exceptional high-temperature strength, and long-term durability. These bolts are ideal for industrial, chemical, and power-generation assemblies exposed to elevated temperatures and aggressive environments. At Walid Stainless, each bolt is manufactured with precision and undergoes rigorous quality control to ensure consistent performance. Clients rely on 347 Bolts for secure, reliable, and long-lasting fastening solutions, making them a preferred choice for demanding high-temperature industrial projects.
Stainless Steel 347 Bolts 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 at elevated temperatures. These bolts typically exhibit tensile strength between 550–700 MPa and hardness around 180–220 HB. The austenitic structure ensures excellent mechanical durability, creep resistance, and dimensional stability under thermal and mechanical stress. 347 Bolts are suitable for industrial, chemical, and high-temperature fastening applications requiring long-term reliability and resistance to oxidation.
