I always understood galling as transfer of metal from one part to another.
For example, transfer of metal from the threads of a bolt hole to threads
of the bolt (or vice versa) as you take it out. Usually a result of
corrosion or extreme friction and is particularly a problem when one of the
metals are soft (like a steel bolt in an aluminum bolt hole).
If corrosion is causing the galling, SS bolts should be better - but that
won't stop an aluminum bolt hole from corroding. I would use anti-seize
compound if you are concerned - the stainless bolts are quite expensive.
