Weston Stainless, Midland, UK-based, is a reliable provider of high-quality stainless steel products offering robust and precision-engineered solutions for numerous industries. Their AISI 304 Stainless Steel 304 Bolts are manufactured using AISI 304 stainless steel, an austenitic alloy that is famous for its excellent corrosion resistance, strength, and durability. Come in various shapes and forms, such as hex bolts, U-bolts, anchor bolts, eye bolts, and carriage bolts, they find extensive applications in construction, marine, chemical, and automotive sectors. The bolts provide enhanced mechanical strength, oxidation resistance, and high-temperature performance, thus being best suited for structural and industrial fastening applications.
Stainless Steel 304 Bolts are composed of 18-20% chromium, 8-10.5% nickel, 2% manganese, 1% silicon, 0.08% carbon, 0.045% phosphorus, and 0.03% sulfur, ensuring excellent corrosion resistance and durability. Their mechanical properties include a tensile strength of 515 MPa, yield strength of 205 MPa, elongation of 40%, and hardness of 90 HRB, providing high strength and reliability. The physical properties feature a density of 8.0 g/cm³, a melting point of 1400-1450°C, and a thermal conductivity of 16.2 W/m·K, making them ideal for high-stress and high-temperature industrial applications.
