Induction tempering

Induction tempering is a heating process that optimises mechanical properties such as toughness and ductility in workpieces that have already been hardened.

What are the benefits?

Temper workpieces in mere minutes or seconds rather than hours, as with furnace tempering
Easy inline integration minimises the number of components in the process
Enable quality control of individual workpieces

Where is it used?

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 equipment is available?

Complete HardLine systems are ideal for many tempering applications. The chief benefit of such systems is that hardening and tempering are performed by one machine. This delivers significant time and cost savings in a small footprint compared to alternative technologies. With furnaces, for example, one furnace often first hardens the workpieces, with a separate furnace then being used for tempering. Stand-alone ENRX Sinac and Minac systems are also used for tempering applications.
