Thread: Color Case Hardening

Howdy All,

Bluing is an oxidizing process that creates a finish that is more rust resistant than untreated steel. This process relies on chemicals and sometimes heat.

Case hardening is a carbonizing process in which the steel is heated to very high temps in a partial vacuum in the presence of organic material such a bone. The organic material provides the carbon which bonds to the surface of the steel in a thin layer or case. This case is much much harder than the steel beneath.

One of the problems encountered with case hardening thin flat pieces of steel is that the steel wants to warp while going through the temperature changes.

Case hardening is indeed beautiful but I don’t think it would make for a good razor.

Then again I could be wrong.

I remain &C,
