Khaled Stainless, located in Cairo, Egypt, specializes in providing Stainless Steel 310 bolts that are designed for high-temperature and oxidation-resistant fastening needs. These bolts are crafted from certified SS 310 bar stock, featuring precise threading, controlled hardness, and strict dimensional tolerances, ensuring they meet industrial standards for thermal-service assemblies. Khaled Stainless offers both standard and custom lengths, along with heat-treatment options and passivation upon request, all while ensuring full material traceability and batch testing. Supplied to furnace builders, petrochemical plants, power generation units, and heavy industries, SS 310 bolts deliver reliable joint integrity in environments where high temperatures and cyclic thermal loading are the norm.
Stainless Steel 310 is a high-chromium, high-nickel austenitic alloy that typically contains around 24–26% chromium and 19–22% nickel, with carbon levels up to about 0.25% and trace amounts of manganese, silicon, and nitrogen. This unique composition provides outstanding oxidation and scaling resistance at elevated temperatures, along with good creep strength. Mechanical properties can vary based on the condition, but generally, tensile strength falls within the 515–750 MPa range, yield strength hovers around 205–310 MPa, and elongation is approximately 30–40%. Bolts can be supplied either annealed or solution-treated; for extended high-temperature use, it’s advisable to consider suitable heat treatment and fastener design to prevent creep-related loosening.
