What is difference between induction hardening and quenching?
Induction hardening is a type of surface hardening in which a metal part is induction-heated and then quenched.
The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to selectively harden areas of a part or assembly without affecting the properties of the part as a whole.
