Thank you all for the help! I am preparing some sodium chromate to test these things on as I am writing this post.
I have done some thorough searching, and think I've (maybe) found a solution to these complicated separations from stainless steel. Could the
chloride solution from HCl dissolution simply be evaporated to get crystals and then dissolved in ethanol?
Please confirm if I am right or wrong, but I believe the nickel and iron chlorides would dissolve while the chromium chloride would stay as a solid.
The ethanol would have to be free of water, of course.
