Khaleed Stainless is a reliable manufacturer and supplier of Stainless Steel 347H Nuts based in Riyadh, Saudi Arabia. We provide top-notch fastening solutions designed for high-temperature and corrosive environments. Stainless Steel 347H is a stabilized austenitic stainless steel known for its high carbon content, which enhances its creep resistance and mechanical strength at elevated temperatures. These nuts find their place in various industries, including chemical processing, oil & gas, power generation, and refineries. With outstanding durability, oxidation resistance, and stability under stress, SS 347H Nuts guarantee long-lasting and dependable fastening performance.
Stainless Steel 347H Nuts are mainly made up of chromium (17–19%), nickel (9–13%), carbon (0.04–0.10%), along with manganese, silicon, phosphorus, and are stabilized with niobium/tantalum to provide exceptional resistance to carbide precipitation. They boast a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an elongation of roughly 40%. These characteristics ensure remarkable high-temperature strength, oxidation resistance up to 1000°C, and improved creep and stress rupture performance, making them ideal for challenging industrial conditions.
