Induction hardening depth at fillet of crankshaft (left) and microstructure in surface-hardened layer (right) Full size image After experimentally optimizing the induction hardening process parameters for the manufacturing of the specimens, the final heat treatment depth reveals an almost identical value of about 3 mm compared to the crankshaft. Crankshaft high cycle bending fatigue research based on the simulation of electromagnetic induction quenching and the mean stress effect Last month we looked into induction hardening of crankshafts and the inherent differences between that process and nitriding. Induction heating is the heating process which is operated on the principle of the electromagnetic induction. The HardLine CIHM-R is a range of EFD Induction robot-type systems for fast, reliable and cost-effective hardening and tempering of crankshafts. Special Purpose Induction Melting Machine for Precious Metals. This results in extremely short cycle times, even with large crankshafts and the patented induction hardening of split pin crankshafts are also possible. Wear resistance behavior of induction hardened parts depends on hardening depth and the magnitude and distribution of residual compressive stress in the surface layer. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Upon quenching, the metal undergoes martensitic transformation, significantly increasing its hardness. With induction, only the part to be hardened is heated. Hardening crankshafts involves consideration of 4 different heating zones - pins, journals, flanges, and shaft - with unique characteristics. The subjected areas had features like oil holes, sharp corners and wide areas.
