What is 321 Stainless Steel Round Bars and Rods?

These bars and rods are made from titanium-stabilized austenitic stainless steels, containing about 17–19% chromium and 9–12% nickel. The addition of titanium helps prevent carbide precipitation during welding and exposure to high temperatures. They boast a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of about 40%. With excellent resistance to oxidation and intergranular corrosion at elevated temperatures, they maintain their mechanical properties up to 870°C, making them ideal for thermal and chemical processing environments.
