Stainless Steel 309H Sheet and Plate is an austenitic stainless steel primarily made up of iron, chromium (22–24%), and nickel (12–15%), featuring a higher carbon content than standard 309 (0.12–0.25%) to boost high-temperature strength. Its mechanical properties showcase excellent tensile and yield strength, superior ductility, and outstanding resistance to oxidation and scaling at elevated temperatures. The increased carbon content enhances creep resistance and high-temperature performance, making it perfect for components that face extreme heat.
