Induction hardening equipment for sale is a heating system used for surface hardening of mechanical parts using the principle of induction heating. By using the skin effect of alternating current and induction heating, the surface layer of steel parts is heated and then cooled and hardened, so that the surface of the parts can be of high hardness and fatigue resistance, while the original toughness of the center is still maintained. Many mechanical parts, such as gears, shafts, pins, and crankshafts, require these characteristics.
