Thin plates and square shafts made from tool steels are very susceptible to warping during the hardening cycles. In order to straighten out these materials post-hardening when they are at their most brittle, ThermTech employs a process involving fixturing these parts during the tempering operation. This is where the material has more ductility and takes a set to a straighter or flatter configuration. This process is called jig tempering. Depending on the straightness tolerance required and the geometry of the parts, it may take several jig tempers to achieve the necessary requirements.
