Weston Stainless is a Midland, UK company, which is one of the foremost distributors of quality stainless steel products for the industrial sectors in need of tough, corrosion-resistant, and high-strength material. Amongst its products, Stainless Steel 304L Fasteners are greatly applied for good mechanical properties and oxidation resistance. 304L grade is an austenitic low-carbon stainless steel alloy composed of iron, 18-20% chromium, 8-12% nickel, and up to 0.03% carbon to provide high weldability and resistance to corrosion. Supplied as bolts, nuts, washers, screws, and studs, these fasteners are specifically ideal for applications in marine, construction, chemicals, and at high temperatures requiring long-term durability.
Stainless Steel 304L Fasteners are composed of iron with 18-20% chromium, 8-12% nickel, a maximum of 0.03% carbon, and small amounts of manganese, silicon, phosphorus, and sulfur, offering excellent corrosion resistance and durability. Their mechanical properties include a tensile strength of 485 MPa, yield strength of 170 MPa, and elongation of 40%, ensuring strong and reliable performance. The physical properties feature a density of 7.9 g/cm³, a melting point of 1400-1450°C, and thermal conductivity of 16.2 W/m·K. These properties make 304L fasteners ideal for marine, chemical, and structural applications requiring high strength and longevity.
