Walid Stainless, headquartered in Tunis, Tunisia, is a leading manufacturer and supplier of high-quality stainless steel products. Among their offerings are Stainless Steel 330 Fasteners, engineered for applications requiring exceptional high-temperature strength, oxidation resistance, and long-term durability. 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 rigorous quality control to ensure consistent performance. Clients rely on 330 Fasteners for secure, reliable, and long-lasting fastening solutions in demanding high-temperature industrial, chemical, and mechanical applications.
Stainless Steel 330 Fasteners are made from a high-alloy austenitic stainless steel containing approximately 34% nickel, 28% chromium, and small amounts of silicon and copper. This composition provides outstanding resistance to oxidation, scaling, and corrosion at elevated temperatures. 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 thermal and mechanical stress. 330 Fasteners are suitable for high-temperature, chemically aggressive, and demanding fastening applications requiring long-term reliability.
