Steve-

It depends on the similarity/dis-similarity of the metals and galvanic
corrosion.  Similar metals will take longer to corrode than those
farther apart on the atomic chart.  Stainless steel has been treated for
hardness (and there are still variations/gradations of stainless steel)
and will take longer to corrode than regular steel bolts.  The problem
lies in the metal used into which the bolts are fastened and the
environment in which the bolts stay.  Everything will corrode, it's just
a matter of time.
