20MnCr5 Round Bars are a type of low-alloy case hardening steel, featuring around 0.17–0.22% carbon, 1.10–1.40% manganese, 0.15–0.35% chromium, along with trace amounts of phosphorus and sulfur. This alloy is renowned for its impressive wear resistance and strength after heat treatment, boasting a tensile strength ranging from 750 to 1000 MPa and a yield strength of about 500 MPa. With excellent hardenability, impact toughness, and fatigue strength, 20MnCr5 is particularly well-suited for carburized components. Its fine grain structure ensures reliable machinability, while its core toughness and surface hardness make it perfect for heavy-duty mechanical applications.
