C45 (1.0503) is a high strength of a high-quality carbon steel, due to poor hardenability, generally used in normalizing state, mechanical performance requirements are higher, the use of quenching and tempering treatment. Cold deformation plastic medium, annealing and normalizing the machinability is better than quenching and tempering. For the manufacture of high strength requirements of the parts, such as gears, shafts, piston pin and the force is not great mechanical parts, forgings, stamping parts and bolts, nuts, pipe connection.
