Stainless Steel 310S Fasteners, made from austenitic stainless steel, offer excellent oxidation resistance, high-temperature strength, and durability. Composed of 24-26% chromium and 19-22% nickel, they withstand extreme heat and corrosive environments. These fasteners come in various shapes, including bolts, nuts, screws, washers, and studs, making them ideal for applications in power plants, petrochemical industries, furnaces, and heat exchangers, ensuring secure and long-lasting connections in demanding industrial conditions
Stainless Steel 310S Fasteners are composed of iron, 24-26% chromium, 19-22% nickel, with small amounts of manganese, silicon, phosphorus, sulfur, and a low carbon content, enhancing oxidation and corrosion resistance. Their mechanical properties include a tensile strength of 515 MPa, yield strength of 205 MPa, and elongation of 40%, ensuring durability in high-stress environments. Physically, they have a density of 7.9 g/cm³, a melting point of 1400-1450°C, and a thermal conductivity of 14.2 W/m·K, making them highly resistant to extreme heat, oxidation, and thermal cycling in demanding industrial applications.
