Description
EN 10083-2 C45 steel (EN 1.0503) is a high strength medium carbon quality steel. Due to poor hardenability, C45 material is generally used in a normalized condition, and 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. The table below gives the C45 steel properties and specifications including chemical composition, mechanical properties and heat treatment. Datasheet 1, The following data sheet lists the C45 chemical composition based on casting analysis.
