Definition of induction annealing

Induction annealing is a type of heat treatment process, in which a metal part is slowly induction-heated to a certain temperature, hold for a sufficient time, and then cooled at a suitable rate. The purpose is to reduce the hardness, improve the ductility and machinability; relieve internal stresses, reduce the tendency of deformation and cracks; refine the grains, adjust the structure, and eliminate the structure defects.
