Weston Stainless, based in Midland, UK, is a prominent stainless steel products supplier offering strong and corrosion-resistant products for different industrial uses. Among its prominent products, Stainless Steel 442 Bolts are well recognized for their superior oxidation resistance, high-temperature strength, and strength. Made of Grade 442, a ferritic stainless steel with high chromium content, these bolts come in different shapes like hex, square, and U-bolts to make them usable in a wide range of applications. With better thermal stability and resistance to scaling when heated to high temperatures, such bolts are suitable for harsh environments that need strength, resistance to wear, and durability.
Stainless Steel 442 Bolts are mainly made up of iron, chromium (18.0-23.0%), carbon (0.2-0.3%), manganese (1.0% max), and silicon (1.0% max), making them more oxidation and corrosion resistant. The bolts have a tensile strength of approximately 550 MPa, yield strength of about 310 MPa, and elongation of approximately 18%. They have a density of 7.7 g/cm³ and melting point of around 1510°C, which provides them with high thermal conductivity and scaling resistance up to 1095°C. The hardness is between 85-95 HRB, which provides high toughness and mechanical strength in the application at elevated temperatures.

A hexagonal head with an integrated flange for improved weight distribution. Provides superior heat resistance and durability for demanding industrial applications.
Threads running the entire length, providing consistent clamping force and high-temperature resistance. They are ideal for high-stress applications requiring durability and strength.
The Stainless Steel 442 Bolts are extensively employed in power generation plants, heat exchangers, furnace fittings, and exhaust systems because they provide high oxidation resistance at high temperatures. They are also utilized in aerospace, automotive, and petrochemical applications where they must have high heat resistance and mechanical strength. They are also used in industrial boilers, structural fasteners, and high-stress mechanical assemblies subject to thermal cycling. Their hardness, resistance to corrosion, and ability to tolerate extreme conditions qualify them for heavy-duty engineering uses in adverse environments.
Stainless Steel 442 Bolts are accompanied by crucial test certificates such as material test reports (MTR), third-party inspection certificates, and EN 10204 3.1 certification to guarantee quality compliance. Secure packaging is accomplished with wooden crates, cartons, or plastic-wrapped bundles to avoid damage during transportation. Reliable and timely delivery guarantees timely delivery of orders in perfect condition, and custom packaging arrangements may be available on request to suit specific industry needs while ensuring product integrity and quality insurance.
