In metallurgy and materials science, annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. It involves heating a material above its recrystallization temperature, maintaining a suitable temperature for an appropriate amount of time and then cooling.
Hongye Intelligent Equipment Technology Co. Ltd supplies a wide range of induction annealing machines. We make customized annealing machine, the frequency and power of the equipment is based on your products material type and size. Generally, frequency selection matches surface layer thickness of the workpiece as below.
