I worked in a plating shop for a few months the last couple of years I was in high school. I remember the only way we stripped chrome off any metal was to acid dip the part. We would set a timer and sumbmerge the part. Let me tell you it some of the most caustic stuff I've ever seen. If you were to fall in the tub they would never find you, that's how strong the acid is. Other than acid dipping I do not know of any way of stipping chrome off of steel. You could use a sander to get rid of a lot of it, but never all of it.
