Zusammenfassung:	A method of making a shaped and hardened steel part has the steps of sequentially heating a steel plate entirely above the AC3 temperature, cooling specific regions of the heated plate without hardening the specific regions, and then engaging the heated plate with the cooled regions in a cool deforming tool with the specific regions out of contact with the deforming tool. This cools the plate where it contacts the tool and deforms the plate with the tool at the specific regions and both cooling and hardening the plate by contact with the tool.
