Tratament de întărire prin inducție of rack

Induction hardening treatment is a hardening treatment of the rack surface.

Generally, after the rack factory undergoes high-frequency treatment, the hardness will meet the requirements for use. The hardness after the modulation treatment in this way cannot reach the hardness of the quenching treatment, but the knowledge of the induction quenching treatment is for the tooth surface.
