I'd say chances are very good. In an earlier part of my career, I've
filled dumpsters with such doors. You'll want to look for a "labled"
door, that is, one with a UL label with some denotation of a 2 hour fire
rating. As time has passed, I've forgotten what the rating is, but
IIRC, it's a "C" labeled door. Look for commercial remodeling sites.
Multi story buildings usually have C labeled doors in stairwells.
Hospitals have large numbers of these doors.
