The composition of Stainless Steel 347H Fasteners includes iron, chromium (17–19%), nickel (9–13%), carbon (0.04–0.10%), along with manganese, silicon, phosphorus, sulfur, and columbium/tantalum for stabilization. They boast a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of 40%, which guarantees toughness and reliability. The high carbon content enhances creep strength, while the combination of chromium and nickel provides excellent oxidation and corrosion resistance at elevated temperatures, making them ideal for critical fastening in challenging environments.
These fasteners are commonly used in high-pressure and high-temperature applications, such as boilers, heat exchangers, and furnace equipment. They are extensively employed in petrochemical plants, refineries, power generation facilities, and thermal processing industries due to their ability to endure prolonged exposure to high heat. Furthermore, these fasteners are also utilized in aerospace, marine, and chemical sectors, ensuring secure and stable connections even in corrosive conditions. Their outstanding resistance to scaling and oxidation guarantees a long service life, making them a trustworthy choice for various applications.
