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. The method continues by providing an inert atmosphere. Then, heating the unfinished shape of the component in the inert atmosphere. 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 fmal geometric dimensions of the components.
