Abstract
A method for forming a component utilizing ultra-high strength steel and components formed by the method. The method includes the step of providing a flat blank of ultra-high strength 22MnB5 steel. The next step of the method is cold forming the flat blank into an unfinished shape of a component while the blank is in an unhardened state. Then, heating the unfinished shape of the component and generating a spline form thereon. The method proceeds by forming a finished shape of the component using a quenching die resulting in a fine-grained martensitic component material structure and enabling net shape processing to establish final geometric dimensions of the component.
