Effect of the Martensitic Transformation on the Stamping Force and Cycle Time of Hot Stamping Parts [PDF]
, 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 ...

Advances in Tribology, Volume 2019, Issue 1, 2019., 2019 Press hardening is widely employed to produce automotive structural and safety components from advanced high‐strength steels. This process depends on friction between the forming tools and the work piece. Wear of the forming tools affects the dimensional accuracy of produced components and reduces their service life. It is therefore desirable to reduce
