...for this Indiana automotive manufacturer, prolonging tool life between sharpenings and reducing the amount of sharpening needed during maintenance. Stamping locking mechanisms for automotive applications-locks on doors, trunk lids, tailgates and the like-can punish tooling, in particular form tools, as these mechanisms commonly are stamped from Type 4130 Cr-Mo steel. These steels, heat-treat hardened, have a 670-MPa yield strength and a 92 Rockwell B hardness, ideal properties when machining drill bits and taps or for fabricating rock-crushing machinery. But try to form them in stamping presses and the form steels can become susceptible to premature wear.
