Stainless Steel 321H rectangular bars are an iron-based alloy, incorporating chromium ranging from 17% to 19% and nickel from 9% to 12%, along with minor amounts of titanium. Owing to this makeup, it resists corrosion, particularly intergranular corrosion. It offers high tensile strength reaching 515-700 MPa, solid yield strength of 205 MPa, and excellent resistance to oxidation at elevated temperatures. Its benefits encompass outstanding strength, remarkable corrosion resistance, stability at high temperatures, and weldability, which collectively suit them for uses in chemical processing, aerospace, or extremely hot environments.
