Induction tempering is a heating process that optimizes mechanical properties such as toughness and ductility in workpieces that have already been hardened.
The main advantage of induction tempering is speed. Induction can temper workpieces in minutes, sometimes even seconds. Furnace tempering typically take hours. And, as induction tempering is perfect for inline integration, it minimizes the number of components in the process. Induction tempering facilitates quality control of individual workpieces. Integrated induction temper stations also save valuable floor space.
Induction tempering is widely employed in the automotive industry to temper surface-hardened components such as shafts, bars and joints. The process is also used in the tube and pipe industry to temper through-hardened workpieces. Induction tempering is sometimes performed in the hardening station, other times in one or several separate temper stations.
What makes it so effective? More and more companies are opting for induction-based hardening solutions.
