Hi Johnny, if you re-read my post I am sure you will agree that we are barking up the same tree. The color case hardening is a process that allows the steel to draw carbon from a reduction atmoshpere (actually the opposite of rust bluing, which employs an oxidation process to form a coating on the steel).
