Induction Hardening Process with Preheat to Eliminate Cracking and Improve Quality of a Large Part with Various Wall Thickness

During an induction hardening process, the electromagnetic field generated by the inductor creates eddy currents that heat a surface layer of the part, followed by spray quenching to convert the austenitized layer to martensite. The critical process param
