Walid Stainless, based in Tunis, Tunisia, is a trusted manufacturer and supplier of high-quality stainless steel products designed to meet industrial and commercial demands. Among their flagship offerings are Stainless Steel 420 Bolts, engineered for strength, durability, and reliable performance. Crafted with precision, these bolts resist wear and corrosion, making them ideal for both indoor and outdoor applications. At Walid Stainless, every product is backed by meticulous quality control and a dedication to excellence. Their commitment to reliability and customer satisfaction ensures clients receive products that combine lasting performance with peace of mind.
Stainless Steel 420 Bolts are made from a high-carbon martensitic stainless steel alloy known for its hardness and corrosion resistance. The alloy contains around 12–14% chromium, which provides rust resistance, and sufficient carbon to achieve high strength after heat treatment. These bolts typically exhibit a tensile strength of 700–850 MPa and a yield strength near 450 MPa, with hardness up to 50 HRC after tempering. The microstructure allows precise machining and excellent wear resistance, making them dependable fasteners for applications where strength and longevity are essential.
