MUKAU FASTENERS, a well-respected manufacturer and supplier located in Kinshasa, Congo, specializes in high-quality Stainless Steel 310/310S Nuts that excel in high-temperature and corrosive settings. Crafted from austenitic stainless steel with a rich blend of chromium and nickel, these nuts offer outstanding resistance to oxidation and heat. The 310S variant features a lower carbon content, which boosts its weldability and minimizes carbide precipitation. MUKAU FASTENERS guarantees that its 310/310S Nuts adhere to strict international standards, making them perfect for industries like petrochemical, furnace manufacturing, and thermal processing, where strength and reliability are paramount.
Stainless Steel 310/310S Nuts are made up of roughly 24–26% chromium, 19–22% nickel, and a maximum of 0.08% carbon (with the 310S variant having even less carbon). These components provide remarkable resistance to oxidation, corrosion, and heat. The nuts boast a tensile strength of around 515 MPa and a yield strength of about 205 MPa, while also maintaining toughness at high temperatures. Their mechanical stability, ductility, and creep strength make them perfect for extended exposure to intense heat and corrosive environments, ensuring durability and reliable performance under thermal stress.
