Introduction to induction hardening

Explains the basic knowledge of induction hardening.

I myself had difficulties with induction hardening in the past, but even when I tried to research things I didn't understand, there were no systematically written books, so I had no choice but to accumulate information that I had heard or researched myself.

When I was struggling with this content, I thought to myself, ``I wish there was a book like this.''
This is something that I have consciously put together so that it will be a content that makes you think.

I try to avoid difficult theoretical topics as much as possible, while still being able to explain things to others. I've written all the knowledge and experience I've gained through my work in this article, so it's perfect for those who are about to get involved in induction hardening, or for those who are currently involved but can't grasp it logically. I think that there.
