Based in Amman, Jordan, Sabra Metals has built a solid reputation as a reliable manufacturer and supplier of high-quality Stainless Steel 321H Round Bars and Rods, specifically designed for high-temperature and pressure applications. These round bars are crafted from titanium-stabilized austenitic stainless steel with a higher carbon content, which not only boosts their strength but also provides excellent resistance to oxidation at elevated temperatures. Sabra Metals is committed to maintaining strict quality control over chemical composition, dimensional accuracy, and surface finish, ensuring they meet international standards. With state-of-the-art manufacturing facilities and a dependable supply chain, the company caters to industries like power generation, petrochemical, oil and gas, and heavy engineering around the globe.
The composition of Stainless Steel 321H Round Bars and Rods includes chromium (17–19%), nickel (9–12%), titanium stabilization, and a higher carbon content compared to SS 321. This unique blend enhances resistance to intergranular corrosion and boosts strength at high temperatures. On the mechanical side, SS 321H showcases higher tensile strength, improved creep resistance, and remarkable toughness. It retains stable mechanical properties even after prolonged exposure to high heat, while also offering good ductility, weldability, and oxidation resistance in challenging thermal environments.
