C45 (1.0503) is a medium-carbon high-quality steel with high strength. Due to poor hardenability, it is generally used in the normalized state. When the mechanical properties are required to be high, the quenching and tempering treatment is adopted. The cold deformation plasticity is medium, and the machinability of annealing and normalizing is better than that of quenching and tempering. It is used for manufacturing parts with high strength requirements, such as gears, shafts, piston pins, and machined parts, forgings, stampings, bolts, nuts, and pipe joints with low stress.
