Yes, what I referred to earlier is a process that is hotter than straw coloring but will someone explain to me where does the blue come from? Not out of thin air. The blue is carbon and as such must come from the metal.


Case hardening as such is a very different process from heat treatment due to heat only. Call me crazy but I still would like someone to tell me where this color comes from. Jerry
