Thread: Sleeving or filling an oversized pivot hole

Exactly right... the same reason they use a Dielectric Union or Insulating Flange

It will happen with any steel. Even Stainless which is specifically designed to prevent or slow down corrosion/oxidation.

If it is kept dry, it will happen very slowly. Electrolytic corrosion (also known as galvanic corrosion) rates are sort of difficult to determine due to variability in the metal properties and environments.
