C30 steel is a medium carbon steel grade that strikes a great balance between strength and machinability. It usually contains around 0.25–0.35% carbon and 0.60–0.90% manganese, along with small amounts of silicon, phosphorus, and sulfur. This blend results in a solid mix of hardness and toughness. C30 steel bars and rods boast a tensile strength ranging from 500–650 MPa, with a yield strength of about 300 MPa, offering moderate ductility. They are ideal for heat treatment processes like quenching and tempering, which boost their hardness, wear resistance, and overall performance in demanding applications.
