Abstract

See full text

A method of quenching a press hardenable steel (PHS) is provided. The method includes preparing a die having a material with a thermal conductivity of at least 40W/(m·K) and placing a blank within the die and simultaneously hot stamping and quenching the blank at a heat transfer coefficient of at least 2,950W/(m2·K). In one form, the step of hot stamping the blank is carried out with greater than 20 MPa of contact pressure between the die and the blank. In another form, the step of hot stamping the blank is carried out with 31 MPa of contact pressure between the die and the blank.
