초록

The Hot Stamping process, which is the hot pressing of steel parts using cold dies. can utilize both case of shaping and high strength due to the hardening effect of rapid quenching during the pressing. We carried out experiments of quenching rate and tempering treatments at temperatures of $200^{\circ}C$ and $300^{\circ}C$ and different soaking times. Tn this study, the mechanical properties and microstructure of micro boron alloyed steels after heat treatments are compared.
