Walid Stainless, based in Tunis, Tunisia, is a trusted manufacturer and supplier of high-quality stainless steel products. Among their premium offerings are Stainless Steel 442 Bolts, engineered for applications that demand superior strength, durability, and corrosion resistance. Known for their excellent performance in harsh environments, these bolts are ideal for industrial, structural, and outdoor applications. Walid Stainless combines advanced manufacturing techniques with strict quality control to ensure every bolt meets exacting standards. Clients rely on their products for fasteners that offer long-lasting performance, precision, and reliability, making 442 bolts a dependable choice for critical projects.
Stainless Steel 442 Bolts are made from a high-chromium, low-carbon martensitic stainless steel alloy, containing approximately 17–19% chromium. This composition gives them excellent resistance to corrosion, oxidation, and high-temperature environments. They are heat-treatable to achieve tensile strength of 650–850 MPa and hardness up to 38–42 HRC. The alloy ensures durability, wear resistance, and dimensional stability, making 442 bolts suitable for demanding mechanical and environmental conditions. Their combination of strength and corrosion resistance allows them to maintain performance even in industrial, marine, and outdoor applications.
