Effect of Mold Heating on High-Temperature Friction and Wear Characteristics of Uncoated 22MnB5 Boron Steel

A self-developed strip-type high-temperature friction and wear test device was used to simulate the high-temperature friction process of uncoated 22MnB5 boron steel under actual hot stamping conditions. The mold was preheated to simulate the temperature increase of the die in the hot stamping proces...
