Effect of the Martensitic Transformation on the Stamping Force and Cycle Time of Hot Stamping Parts [PDF]
Metals, 2018 Stamping dies perform two functions in the hot stamping process of body-in-white components. Firstly, they form the steel sheet into the desired shape and, secondly, they quench the steel at a cooling rate that leads to hardening by means of the ...
