INTEGRATIVE TREATING PROCESS FOR PUNCHING STEEL |
摘要 |
A processing method is provided integrating hot stamping and controllable subsequent heat treatment in the technical field of hot working for steels. It includes the steps of selecting and preparing a steel blank, hot stamping treatment, controllable temperature quenching, adjusting the temperature of the steel blank to a tempering temperature and fine stamping at the same time. The invention combines the hot stamping and controllable heat treatment to improve the strength of material with precise plastic deformation and save energy as well. The tensile strength of the processed steel is greater than 1900Ma. |
