Abstract
A component and method for forming the component utilizing ultra-high strength steel is provided. The method includes the steps of providing a blank of ultra-high strength steel and forming the blank into an unfinished component. Next, heating the unfinished component and moving an inner tooling member and an outer tooling member relative to one another to sandwich the heated component therebetween. Further, moving a punch member from a withdrawn, unactuated position to an extended, actuated position to contact the component while sandwiched between the inner and outer tooling members to form a feature including at least one of a thickened region having an increased thickness relative to an adjacent region, a recessed annular groove, a recessed pocket, a through hole, a flange, a through hole having a tab extending outwardly therefrom, or spline teeth. Then, quenching the feature.
