Abstract: Components and methods for forming components utilizing ultra-high strength steel are provided. A first method includes the steps of providing a blank of ultra-high strength steel, cold forming the blank into an unfinished component, and applying a coating to the outer surface of the unfinished component that is adapted to inhibit the formation of a ferrite soft layer on the component during heating thereof. A second method includes the steps of providing a blank of heavy gauge thickness ultra-high strength steel, cold forming the blank into a finished component, heating the finished component and quenching the component without the use of tooling.

Abstract: A novel method of manufacturing a toothed disc is taught wherein the teeth can be cold formed to a relatively high set of tolerances in a relatively time-efficient manner. A cold-formed disc blank with an annular thickened ring about its periphery is forced through a set of tooth forming rollers which engage the annular thickened ring. As the blank is forced through the set of rollers, the rollers cold forming tooth structures in the annular ring. In some circumstances, the tooth structure can be a final desired tooth profile and in other circumstances, the disc blank may be forced through two or more different sets of tooth forming rollers, each set of tooth forming rollers contributing to the forming of the final, desired tooth profile.
