Why would it not last on something that is only occasionally in contact with liquid? Stainless steel is what the impeller shaft is made of in the majority of all aquarium related pumps.
Cheaper pumps use stainless, better pumps use ceramic. just for giggles, place a piece of stainless steel over some running saltwater for a couple of weeks and see what happens. Saltwater is some of the most corrosive stuff on the planet. "stainless" steel is just that when in contact with most things but when in contact with saltwater it will rust. Try it.
