Weston Stainless, Midland, UK is a reliable source of high-quality stainless steel fasteners for industries that need long-lasting and corrosion-resistant solutions. One of its high-end products, Stainless Steel 405 Fasteners, is produced from grade 405 stainless steel, a ferritic alloy with enhanced oxidation resistance and lower hardening properties. The fasteners are supplied in bolts, nuts, washers, screws, and studs to provide versatility in industrial applications. Produced with a content high in iron and chromium, these fasteners possess good machinability, moderate corrosion resistance, and resistance to high temperatures, which makes them suited for the automotive sector, power plants, and chemical industries.
Stainless Steel 405 Fasteners have 11.5-14.5% chromium, 0.08% carbon, and traces of manganese, silicon, and phosphorus, and hence they are resistant to corrosion and scaling. Their mechanical characteristics are tensile strength of about 415 MPa, yield strength of 205 MPa, and hardness of 85 HRB, offering high durability in conditions of high stress. The density of 405 stainless steel is 7.75 g/cm³, and the melting point is about 1500°C, ensuring reliability in high-temperature applications. The fasteners also have high thermal conductivity and controlled expansion, making them ideal for heat-resistant assemblies.
