Stainless Steel 321H Round Bars and Rods are a type of austenitic stainless steel that’s stabilized with titanium to prevent intergranular corrosion and boost high-temperature performance. Typically, their composition features 17–19% chromium, 9–12% nickel, 0.04–0.10% carbon, along with trace amounts of manganese, silicon, and titanium. These bars and rods are known for their impressive tensile strength, high-temperature stability, and good weldability. In terms of mechanics, they boast a tensile strength ranging from 515 to 750 MPa, a yield strength of about 205 to 275 MPa, and a hardness of approximately 170 to 200 HB. Their unique blend of corrosion resistance and thermal stability makes them perfect for demanding industrial and engineering applications.
