321H Hollow Bar Stainless Steel is an austenitic stainless steel consisting mainly of chromium (17–19%), nickel (9–12%), and titanium (≥5xC%) for stabilization purposes. The “H” designation represents increased carbon content to improve high-temperature strength. It provides mechanical properties like tensile strength of approximately 515 MPa, a yield strength of 205 MPa, and excellent creep resistance. Stainless Steel 321H Hollow Bar excels at excellent weldability and intergranular corrosion resistance, which makes it ideal for use in elevated temperature service in hostile environments.
