C45 (1.0503) is a medium-carbon high-quality steel with higher strength. Due to poor hardenability, it is generally used in a normalized state. When the mechanical performance requirements are higher, quenching and tempering treatment is used. The cold deformation plasticity is medium, and the machinability of annealing and normalizing is better than that of quenching and tempering. It is used to manufacture parts with high strength requirements, such as gears, shafts, piston pins, etc., as well as machined parts, forgings, stamping parts, bolts, nuts, and pipe joints that are not subject to great stress.
1. After heat treatment, the hardness and wear resistance can be improved.2. The hardness is appropriate during annealing and the machinability is good.3. Its raw materials are very common and therefore easy to find, so the production cost is not high.| C45 carbon steel plate chemical composition | |||||||
