No museums that I know of, but some of the larger "houses" (boiler houses, blast furnaces, turbo house, Fab shops) are littered with photos of the early US Steel years. I once saw an old book that had incredible pics. Some of the old timers have tons of stories. Officially, you'd have to contact them and ask permission; I wish you luck.
