Walid Stainless, headquartered in Tunis, Tunisia, is a leading manufacturer and supplier of high-quality stainless steel products. Among their offerings are Stainless Steel 347 Stud Bolts, designed for applications requiring excellent high-temperature strength, corrosion resistance, and long-term durability. These stud bolts are ideal for industrial, chemical, and power-generation assemblies exposed to elevated temperatures and oxidizing environments. Each stud bolt is manufactured with precision and undergoes rigorous quality control to ensure consistent performance. Clients rely on 347 Stud Bolts for secure, reliable, and long-lasting fastening solutions in demanding high-temperature industrial and mechanical projects.
Stainless Steel 347 Stud 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 creep resistance, dimensional stability, and mechanical durability under thermal and mechanical stress. 347 Stud Bolts are suitable for high-temperature, chemically aggressive fastening applications requiring long-term reliability and resistance to oxidation.
