Weston Stainless, based in Midland, UK, is a leading manufacturer and supplier of high-quality stainless steel fasteners, providing durable and corrosion-resistant solutions for industries such as petrochemical, marine, construction, and power generation. Among its range of products, Stainless Steel 316 Bolts are highly valued for their excellent corrosion resistance and strength. Made from Grade 316 stainless steel, these bolts are available in various shapes, including hex, U-bolts, carriage, and anchor bolts. Composed of iron, 16-18% chromium, 10-14% nickel, 2-3% molybdenum, and low carbon content, they offer superior resistance to chloride environments, making them ideal for marine and chemical processing applications.
Stainless Steel 316 Bolts are composed of iron, 16-18% chromium, 10-14% nickel, 2-3% molybdenum, 2% manganese, 0.75% silicon, 0.08% carbon, 0.045% phosphorus, and 0.03% sulfur. They exhibit excellent mechanical properties, including a tensile strength of approximately 515 MPa, yield strength of 205 MPa, and an elongation of 40%. Their physical properties include a density of 7.98 g/cm³, a melting point of 1375-1400°C, and high resistance to chloride-induced corrosion. These properties make them ideal for marine, chemical, and high-moisture environments requiring superior durability and oxidation resistance.
