Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of high-quality stainless steel products. Among their offerings are Stainless Steel 422 Fasteners, engineered for applications requiring high strength, excellent corrosion resistance, and durability in challenging industrial environments. These fasteners are ideal for mechanical, chemical, and power-generation assemblies exposed to moderate temperatures and corrosive conditions. Each fastener is manufactured with precision and undergoes strict quality control to ensure consistent performance. Clients rely on 422 Fasteners for secure, long-lasting, and reliable fastening solutions in demanding industrial, mechanical, and chemical projects.
Stainless Steel 422 Fasteners are made from a martensitic stainless steel alloy containing approximately 17–18% chromium and 0.4–0.5% carbon. This composition provides high tensile strength, hardness, and moderate corrosion resistance. These fasteners typically exhibit tensile strength between 700–800 MPa and hardness around 50–55 HRC after heat treatment. The martensitic structure ensures excellent wear resistance, mechanical durability, and dimensional stability under stress. 422 Fasteners are suitable for industrial, mechanical, and chemical applications requiring secure fastening, high strength, and long-term reliability.
