Stainless Steel 321H is an austenitic stainless steel alloy containing approximately 17-19% chromium, 9-12% nickel and 2.0-2.5% titanium It provides good resistance to high temperature oxidation and corrosion, making it suitable for high temperature applications. Its characteristics include good tensile strength, good weldability and intergranular corrosion resistance. The addition of titanium adds stability to the material, prevents carbide precipitation, and overall durability. This makes stainless steel 321H ideal for use in chemical processing, aerospace and exhaust systems.
