What is 321 Stainless Steel Round Bars and Rods?

The composition of Stainless Steel 321 Round Bars and Rods includes chromium (17–19%), nickel (9–12%), carbon (up to 0.08%), along with manganese, silicon, and stabilizing titanium. The addition of titanium helps prevent carbide precipitation during welding, boosting both corrosion resistance and structural stability. These bars boast a tensile strength of about 515 MPa, a yield strength of around 205 MPa, and an elongation of 40%. They deliver impressive mechanical strength, high-temperature stability, and creep resistance, making them ideal for long-term use in harsh and elevated-temperature settings without sacrificing durability.
