Özet

Steel is one of the most common metals. In the die business, cold work tool steels (CWTS) are widely preferred. In addition to regular CWTS, next-generation CWTS have recently been used. This study investigates the use of classic and two new-generation CWTS as punch materials in pressing electric motor rotors. It has been discovered that new-generation CWTS have a longer lifespan than traditional ones. SEM and X-ray spectroscopy (EDS) were used to examine the microstructures, and the carbide structures they could produce were analyzed using FactSage® 8.2 thermodynamic software. The formation of fine and uniformly dispersed carbide structures and numerous carbide structures has been observed in the latest generation CWTS. These were thought to be the causes behind the CWTS’s lengthy service life.
