The function of induction hardening after induction hardening

1. Surface hardness of the workpiece after quenching: The surface of the workpiece is quenched by high- and medium-frequency induction heating of a high-frequency quenching machine, and the surface hardness of the workpiece is generally about 2 to 3 HRC higher than that of the usually quenched workpiece.

1. The wear resistance of the workpiece after quenching: After the workpiece is subjected to high frequency quenching, its wear resistance will be much higher than that of ordinary quenching. The main reason for this is because the hardened layer has fine martensite grains. The carbide has a high degree of dispersion and a relatively high hardness.
