Product Name: | Carbon steel 1045/K1045/45# Round bar. |
Product characteristics: | 1045 refers to the medium carbon quenched and tempered structure Steel. The cold plasticity of this steel is average, and annealing and normalizing are slightly better than quenching and tempering. It has high strength and good machinability. After appropriate heat treatment, it can obtain a certain degree of toughness, plasticity, and wear resistance |
