About 0.42–0.50% carbon and 0.50–0.80% manganese are normally present in carbon steel C45, along with trace amounts of silicon, sulphur, and phosphorus. It is a medium carbon steel grade offering good tensile strength, toughness, and wear resistance. With a tensile strength ranging from 570 to 700 MPa, C45 can be surface-hardened using induction or flame techniques. It is frequently supplied in rolled or normalised form and has a moderate machinability. Its strength-to-weight ratio and ability to be heat-treated make it ideal for manufacturing components exposed to stress and impact.
