Steel performance did vary over time.  The “coal” (and other) RRs were constantly looking for something better to build their hoppers from, particularly for slope and side sheets.  I have read plenty of correspondence in which this exact issue is discussed.  Over time, the steel companies supplied the RRs and builders, with steel whose properties were increasingly resistant to corrosion, “Cor-Ten” being one USS product. 

         Elden states it very well. It is interesting to read articles in _Railway Age_ in the first decade or two of the 20th century, when there were plenty of railroad people skeptical that steel freight cars would "catch on" because of the severe corrosion. Many surface treatments and paint formulas were discussed, but as Elden says, the real key was different steel compositions. There were and are LOTS of them, with Cor-Ten being just one.
