More on Black Finish on Stainless
One of our readers has suggested another process for getting a black finish on 430 stainless steel.
In the April issue, I answered a question regarding getting a black finish on 430 stainless steel. I suggested the classic hot black oxide process. One of our readers has suggested that another process might also work: using a thermochemical treatment such as shallow nitriding followed by post oxidation. The magnetite that is formed on the surface is black and has good corrosion resistance. Thanks to E.R. for this suggestion.
