Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of high-temperature stainless steel fastening solutions for demanding industrial applications. Their Stainless Steel 310S Nuts are engineered for environments where extreme heat, oxidation, and corrosion resistance are essential. With a low carbon composition, these nuts provide excellent thermal stability and weldability. Manufactured using precision-controlled processes and strict quality inspections, Walid Stainless ensures consistent threading, dependable strength, and long service life. Customers rely on Stainless Steel 310S Nuts for secure fastening and reliable performance in high-temperature industrial systems.
Stainless Steel 310S Nuts are produced from an austenitic stainless steel alloy containing approximately 24–26% chromium and 19–22% nickel, with low carbon content to minimize carbide precipitation. This composition delivers outstanding oxidation resistance and mechanical stability at temperatures up to 1100°C. These nuts typically exhibit strength consistent with 310S-grade fasteners and hardness around 170–200 HB. The austenitic structure ensures excellent toughness, corrosion resistance, and durability in continuous high-temperature service.
