MUKAU FASTENERS, a top-notch manufacturer and supplier located in Kinshasa, Congo, specializes in high-quality Stainless Steel 310/310S Fasteners that are built to perform exceptionally well in high-temperature and corrosive settings. Crafted from an austenitic stainless steel alloy rich in chromium and nickel, these fasteners offer outstanding oxidation and heat resistance. The 310S grade, which has a lower carbon content, enhances weldability and minimizes carbide precipitation. MUKAU FASTENERS is committed to precision engineering and follows international standards closely, providing 310/310S Fasteners that ensure durability, mechanical strength, and long-lasting stability for critical industrial applications like furnaces, refineries, and power plants.
Stainless Steel 310/310S Fasteners are made up of about 24–26% chromium, 19–22% nickel, and a maximum carbon content of 0.08%, with the 310S grade featuring lower carbon for improved weldability. They boast a tensile strength of around 515 MPa and a yield strength close to 205 MPa, along with excellent oxidation resistance up to 1100°C. The high levels of chromium and nickel provide remarkable protection against corrosion, scaling, and thermal fatigue, while the alloy’s mechanical stability and creep strength make these fasteners perfect for extreme temperature and pressure situations.
