Induction hardening is a form of heat treating where a metal part is heated by induction and then quenched. Induction hardening and heat treating are ideal for a wide variety of applications in the transportation, aerospace, and energy industries, for processes such as through hardening and case hardening.
Through hardening treats the entire part and is used on medium and high carbon steels for moderate strength and surface hardness. Case hardening treats the part’s surface area and some of the interior area, according to the depth of hardening requirements of the application.
The primary benefit of induction heating for hardening is that it is very rapid. Induction may take seconds or minutes whereas a furnace can take hours or even days. Continue reading to check out some application notes and learn more about how induction can benefit your hardening process.

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. The material may be a metal such as brass, aluminum, copper or steel or it can be a semiconductor such as silicon carbide,carbon or graphite. To heat non-conductive materials such as plastics or glass, induction is used to heat an electrically-conductive susceptor, typically graphite, which then transfers the heat to the non-conducting material.

Heat Treating Solutions from Ambrell Hardening
A superior alternative to thermo-chemical heating, induction heating provides faster, more consistent heat for heat treating applications. The process relies on electrical currents to produce heat within the component—heat that remains confined to precisely targeted areas.
