Weston Stainless is a Midland, UK-based reliable manufacturer and supplier of excellent stainless steel products to construction, automotive, marine, and chemical processing industries. It offers long-lasting, resistant solutions to be used in numerous industrial processes. Among its notable products is Stainless Steel 304H Bolts, which is crafted with high-carbon 304H stainless steel for exceptional strength and heat resistance. They come in hex, square, U-bolts, eye bolts, anchor bolts, and carriage bolt configurations, which make them suitable for heavy–duty, structural, and high–temperature fastening applications in harsh industrial settings.
Stainless Steel 304H Bolts are made up of 18-20% chromium, 8-10.5% nickel, 0.04-0.10% carbon, ≤2% manganese, ≤1% silicon, ≤0.045% phosphorus, and ≤0.03% sulfur, providing high corrosion resistance and high-temperature strength. Their mechanical properties have a tensile strength of 515 MPa, yield strength of 205 MPa, and elongation of 40%, providing durability in stressful applications. The physical characteristics have a density of 8.0 g/cm³, a melting interval of 1399-1454°C, and thermal conductivity of 16.2 W/m·K, and hence are ideal for use in heat exchangers, boilers, pressure vessels, and structural frames that need enhanced mechanical and thermal stability.
