Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of premium stainless steel products. Among their offerings are Stainless Steel 442 Stud Bolts, designed for applications requiring excellent corrosion resistance, high-temperature strength, and long-term durability. These stud bolts are ideal for industrial, chemical, and power-generation assemblies exposed to harsh environments and elevated temperatures. At Walid Stainless, each stud bolt is manufactured with precision and undergoes strict quality control to ensure consistent performance. Clients rely on 442 Stud Bolts for secure, reliable, and long-lasting fastening solutions in demanding industrial and high-temperature applications.
Stainless Steel 442 Stud Bolts are made from a ferritic stainless steel alloy containing approximately 17–18% chromium and low carbon content. This composition provides excellent corrosion resistance, high-temperature strength, and good resistance to oxidation. These bolts typically exhibit tensile strength between 600–750 MPa and hardness around 200–240 HB. The ferritic structure ensures dimensional stability, mechanical durability, and resistance to creep under elevated temperatures. 442 Stud Bolts are suitable for industrial, chemical, and high-temperature fastening applications requiring long-term reliability, mechanical strength, and corrosion resistance.
