Stainless Steel 321 / 321H Sheets & Plates are manufactured from an austenitic stainless steel alloy stabilized with titanium, with controlled amounts of chromium, nickel, carbon, manganese, silicon, and other alloying elements. The titanium addition helps reduce the risk of chromium carbide precipitation during prolonged exposure to elevated temperatures, allowing the material to maintain good corrosion resistance and structural stability in high-temperature service. Chromium provides resistance to oxidation and general corrosion, while nickel contributes to the alloy’s toughness, ductility, and overall corrosion performance. The stabilized structure of Stainless Steel 321 makes it suitable for applications involving welding and elevated-temperature operation, while the higher carbon content of 321H is intended to provide improved high-temperature strength compared with standard 321 in appropriate service conditions.
