Home > Stainless Steel 314 Stud Bolts
Stainless Steel 314 Stud Bolts are top-notch fastening components crafted for extreme high-temperature settings and tough industrial conditions. Made from Grade 314 stainless steel, these bolts boast remarkable resistance to oxidation, scaling, and thermal fatigue. Thanks to their high chromium and nickel content, they excel in environments with continuous heat exposure, making them perfect for demanding tasks. You’ll find Stainless Steel 314 Stud Bolts commonly used in furnaces, heat-treating equipment, petrochemical systems, and high-temperature machinery. Their durability, stability, and long lifespan make them a go-to choice for industries that need strong and heat-resistant fastening solutions.
These stud bolts are made up of iron, chromium (24–26%), nickel (19–22%), and a touch of silicon, which greatly boosts their oxidation resistance at high temperatures. This alloy delivers impressive tensile strength, high yield strength, and excellent resistance to thermal shock. The added silicon enhances scaling resistance and improves performance under continuous heat exposure. These bolts can maintain their structural integrity at temperatures reaching up to 1150°C, ensuring consistent mechanical strength and durability. Their unique composition makes them perfect for applications that require outstanding heat, corrosion, and oxidation resistance.
