Color Case Hardening - Magzter

There are two basic types of color case hardening. One is done by a chemical process using cyanide. The other method consists of packing the part in a dry mixture, baking it to very high temperature and then quenching it suddenly in water. This second method is called pack hardening. It’s a lot more complicated than this paragraph might indicate.
