Dissimilar metals in air conditioned environment

For a dry interior air conditioned condition not exposed to the elements, is there a corrosion or galvanic action concern for installing stainless steel sheet on top of inorganically primed or galvanized carbon steel furring ( 1.5 inches wide at 2'-0" on center ) with stainless steel fasteners?

Kenneth, How can there be any 'corrosion' in a dry scenario ... you need moisture. Example ... kitchen knives ... some of which have silver plated handles (maybe even some solid silver spoons) ... why don't they show signs of the blades being attacked? Ah, you might say. But some blades do show some pitting. Yes, but that's due to the dishwasher liquid and using mild steel (but nice and sharp) knife blades.
