Heat Treatment Quenching Method to Reduce Distortion NitridingProperties and characteristicsof the nitrided layer varydepending on nitriding methodsand conditions. Please choosethe type of nitriding accordingto the right figure. As the cooling rate of quenching becomes faster, the heattreatedmicrostructure becomes finer and the toughness isimproved. However, the distortion after heat treatmentincreases. By optimizing the quenching pattern, Hitachi MetalsGroup has establishied heat treatment method which not onlyreduce distortion but also improve toughness.
