Weston Stainless, based in Midland, UK, is a renowned supplier of high-quality premium stainless steel products offering superior fastening solutions for industrial uses. Its standout product, Stainless Steel 436 Bolts, is a ferritic stainless steel fastener that boasts superior corrosion resistance, thermal stability, and good machinability. Manufactured from Grade 436 stainless steel, these bolts are available in various shapes, including hex, square, and U-bolts, ensuring versatility in fastening applications. With added molybdenum content, Stainless Steel 436 Bolts offer enhanced resistance to stress corrosion cracking, oxidation, and high temperatures, making them ideal for demanding industrial and structural applications.
Stainless Steel 436 Bolts consist of iron, 16.0-18.0% chromium, 0.75-1.25% molybdenum, 0.12% max carbon, 1.0% max manganese, and 1.0% max silicon, which makes them more corrosion and oxidation resistant. These bolts have a tensile strength of around 450 MPa, a yield strength of about 280 MPa, and an elongation of around 22%. With 7.7 g/cm³ density and a melting point of around 1480°C, they have excellent thermal conductivity and a moderate hardness between 85-90 HRB. Their superior mechanical properties guarantee long-lasting performance in high temperature and high-stress environments.
