Weston Stainless, based in Midland, UK, is a trusted supplier of stainless steel products, serving industries with high-quality materials and expert solutions. Stainless Steel 310 Bolts, made from an austenitic stainless steel alloy with 24-26% chromium and 19-21% nickel, offer excellent high-temperature strength and corrosion resistance. These bolts are commonly available in hexagonal shapes and conform to ASTM A276 standards. Their robust composition allows them to withstand oxidation and perform efficiently in temperatures up to 2000°F (1093°C), making them ideal for applications in heat treatment equipment, power plants, and chemical processing industries.
Stainless Steel 310 Bolts are composed of approximately 24-26% chromium, 19-21% nickel, 2% manganese, 1% silicon, and trace amounts of carbon, phosphorus, and sulfur. Their mechanical properties include a tensile strength of around 515 MPa, yield strength of 205 MPa, and an elongation of 40%. The Brinell hardness is approximately 201 HB. Physically, they have a density of 7.9 g/cm³, a melting point of about 1400-1450°C, and a thermal conductivity of 15.1 W/m·K, offering excellent resistance to oxidation and high-temperature environments.
