A drop of hydrochloric (muriatic) acid will react with chrome dissolving it with release of bubbles, a green salt and leaving it dull in a matter of 1 min or less. No visible action or change on steels.

You can use a copper sulphate ⇦ on eBay or Amazon [affil link] solution. An indication of red colour on steel. Good luck .
