In the case of steel, this process is performed with induction heater by heating the material (generally until glowing) for a while and then slowly letting it cool to room temperature in still air. In this fashion, the steel is softened and prepared for further work—such as shaping, stamping, or forming.
Induction annealing has many benefits. The heat is generated directly in the material, leading to high efficiency and low energy costs. It is also a fast and controllable process, which will improve your throughput. And the heat is very accurate—crucial to meet today's stringent quality standards. The right heat in the right place reforms the material structure and reduces internal stresses in just the way you want.
