Title:
An investigation of the blanking process of the quenchable boron alloyed steel 22MnB5 before and after hot stamping process 
Abstract:
Recently, one of the most important issues in the automotive industry is lightweight construction. While maintaining safety standards, the fuel consumption can be decreased by reducing the weight of the vehicle. To manufacture lightweight vehicle components with high strength, hot stamping with quenchable boron steels is becoming more common in automotive industries. However, the high strength achieved in the press-hardened parts causes severe wear and sometimes unexpected premature failure in t...    »
