Stainless Steel Round Bar 321 is an austenitic chromium-nickel stainless steel known for its excellent resistance to intergranular corrosion after exposure to temperatures within the chromium carbide precipitation range. This makes it ideal for high-temperature applications up to approximately 1500°F. The addition of titanium stabilizes the steel, preventing carbide precipitation and enhancing its weldability. It's commonly used in aerospace components, furnace parts, and chemical processing equipment where high strength and corrosion resistance are crucial.
