ABSTRACT:
A bumper beam for vehicles is formed from cold-rolled sheet steel having an initial tensile strength of approximately 70 ksi. The steel sheet is roll formed in a desired cross-section and swept into a curvature corresponding to the vehicle requirements before the steel sheet is heat treated by induction heat and quenched to provide a bumper beam having a tensile strength from 100 ksi up to approximately 260 ksi.
