Summary: Inductors used to selectively harden steel parts are exposed to brutal conditions. A typical application will mix powerful electromagnetic energy, spinning red hot steel, a flood of water, oily smoke and steam. In the middle of it all sits an inductor. The survival of inductors built to withstand the application and environment is the topic of discussion.
