Stainless Steel 310/310S Bolts have about 25% of chromium and 20% nickel, which gives excellent corrosion resistance and superior heat tolerance. These bolts provide tensile strength of about 515 MPa, yield strength of 515 MPa, and elongation of 40%. Designed for elevated temperature service through 1100°C (2012°F), they are resistant to oxidation, sulfur attack, thermal fatigue, and cyclic heating. The 310S type, with a lower carbon content, has improved weldability and less carbide precipitation. These mechanical and thermal characteristics of 310/310S bolts make them well suited for long-term exposure in hostile heat and chemicals.
Stainless Steel 310/310S Bolts are a perfect choice for high-temperature and corrosive environments, particularly where oxidation resistance and mechanical stability are absolutely necessary. The bolts find extensive use in industrial furnaces, kilns, heat treatment facilities, thermal processing equipment, and gas turbine combustion chambers. They‘re also an essential component in power generation, petroleum refining, and chemical process plants, ensuring safe fastening in exposed areas to debris, acidic gases, and harsh heat. Their sulfur-resistant, thermal cycling, and oxidation scaling resistance guarantee reliable performance and structure integrity under a wide range of high-stress industrial conditions.
