Stainless Steel 321 Rectangular Bars are a type of titanium-stabilized austenitic stainless steel, containing about 17–19% chromium, 9–12% nickel, and titanium levels that are at least five times the carbon content to avoid carbide precipitation. This alloy boasts a tensile strength of around 515 MPa and a minimum yield strength of 205 MPa, along with impressive oxidation resistance up to 870°C. The titanium stabilization significantly boosts its resistance to intergranular corrosion, particularly after welding, making it a great choice for long-term use in high-temperature settings.
