Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of premium stainless steel products. Among their offerings are Stainless Steel 347H Fasteners, engineered for applications requiring exceptional high-temperature strength, corrosion resistance, and long-term reliability. These fasteners are ideal for industrial, chemical, and power-generation assemblies exposed to extreme heat and oxidizing environments. Each fastener is manufactured with precision and undergoes strict quality control to ensure consistent performance. Clients rely on 347H Fasteners for secure, durable, and dependable fastening solutions in demanding high-temperature and industrial applications.
Stainless Steel 347H Fasteners are made from a titanium-stabilized austenitic stainless steel alloy containing approximately 17–19% chromium, 9–13% nickel, and a higher carbon content (0.04–0.10%) than standard 347 to improve high-temperature strength. Titanium stabilization prevents sensitization and enhances corrosion resistance during thermal 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, making 347H Fasteners suitable for high-temperature, chemical, and industrial applications.
