Weston Stainless, Midland, UK-based, is a prominent provider of stainless steel products of superior quality, offering reliable and precision-designed solutions for industrial use. Its top-end products include Stud Bolts in Stainless Steel 446, highly resistant against oxidation, scaling, and high-temperature corrosion. These stud bolts fall under Grade 446 and are provided in different shapes and sizes for compatibility with industrial needs. Produced from ferritic stainless steel, they possess superior strength, heat resistance, and durability, which makes them suitable for high-temperature conditions and applications demanding superior mechanical stability.
446 Stud Bolts made of stainless steel consist primarily of iron with a high chromium content (23-27%) for superior corrosion and oxidation resistance. They also have minute amounts of carbon, manganese, silicon, and trace elements that improve their structural integrity. With a tensile strength of approximately 550 MPa, yield strength of about 310 MPa, and elongation of 20%, these bolts have very good mechanical performance. Their physical properties are a density of approximately 7.7 g/cm³ and high thermal conductivity, providing stability in extreme heat and oxidative environments.

Designed for high-stress, high-temperature applications, offering superior strength, durability, and corrosion resistance.
Excellent high-temperature and corrosion resistance, ideal for heavy-duty industrial applications requiring robust performance.
Stainless Steel 446 Stud Bolts find extensive application in services that demand enhanced heat and corrosion resistance, like power plants, heat exchangers, boilers, and furnace parts. They are also used in petrochemical plants, cement plants, and incinerators, where stability at high temperatures is critical. The stud bolts are used extensively in exhaust systems, refractory anchors, and thermal processing equipment because they can withstand aggressive environments. Their high oxidation resistance and mechanical strength make them the best choice for applications involving prolonged exposure to high temperatures.
Stainless Steel 446 Stud Bolts are supplied with mill test certificates like EN 10204 3.1 or 3.2 to ensure adherence to industrial standards of quality. They are properly packed in wooden crates, bubble wraps, or plastic-capped ends to avoid damage during shipping. Delivery is based on the size of the order and geographical location, with effective logistics ensuring prompt dispatch. Special packaging can be arranged as per requirement to cater to the needs of the client, ensuring that the bolts are delivered in the best possible state.
