Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of premium stainless steel products. Among their offerings are Stainless Steel 317L Fasteners, engineered for applications requiring superior corrosion resistance, durability, and long-term reliability. These fasteners are ideal for chemical, pharmaceutical, marine, and industrial assemblies exposed to harsh corrosive environments. Each fastener is manufactured with precision and undergoes strict quality control to ensure consistent performance. Clients rely on 317L Fasteners for secure, reliable, and long-lasting fastening solutions in demanding chemical, marine, and industrial applications where high corrosion resistance is essential.
Stainless Steel 317L Fasteners are made from a low-carbon austenitic stainless steel alloy containing approximately 18% chromium, 13% nickel, and 4% molybdenum. The low carbon content minimizes carbide precipitation, enhancing resistance to intergranular corrosion. These fasteners typically exhibit tensile strength between 550–700 MPa and hardness around 170–210 HB. The austenitic structure provides excellent mechanical durability, toughness, and dimensional stability under thermal and mechanical stress. 317L Fasteners are suitable for chemical, marine, and industrial applications where long-term reliability, corrosion resistance, and strength are critical.
