Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of premium stainless steel products. Among their offerings are Stainless Steel 446 Fasteners, engineered for applications requiring exceptional corrosion resistance, high-temperature strength, and long-term durability. These fasteners are ideal for industrial, chemical, and power-generation assemblies exposed to extreme heat, oxidizing environments, or harsh marine conditions. Each fastener is manufactured with precision and undergoes strict quality control to ensure consistent performance. Clients rely on 446 Fasteners for secure, durable, and dependable fastening solutions in demanding high-temperature, chemical, and industrial applications.
Stainless Steel 446 Fasteners are made from a ferritic stainless steel alloy containing approximately 23–27% chromium with low carbon content. This composition provides excellent corrosion resistance, high oxidation resistance at elevated temperatures, and moderate mechanical strength. These fasteners typically exhibit tensile strength between 500–650 MPa and hardness around 180–220 HB. The ferritic structure ensures dimensional stability, excellent resistance to scaling, and durability under thermal stress. 446 Fasteners are suitable for industrial, chemical, marine, and high-temperature applications where long-term corrosion resistance and mechanical reliability are essential.
