Seeking advice on reagent to etch 17-4 stainless steel
I am David Jones, Mechanical Engineer for a company which reverse engineers and designs various mechanical equipment. I am seeking information regarding chemical used for etching stainless steel 17-4. I would like to use Viella's Reagent, however I do not have any Glycerol or picric acid, and would like to stay away from picric. I would like to know if anyone can assist me with possibly finding another chemical composition that may work and allow me to optically analyze grain structures of my sample.
Thanks,
