I think that Ralph is correct here.
Actually Stainless can and does rust.  I'm no expert but I did work in a
boatyard as a welder and metal fabricator and I have definitely seen rusted
pitted stainless steel.  There are many different grades and I'm sure you
could research this fairly quickly on the web.  I believe that rust
resistance varies with chromium and nickel content.  Not sure, there must be
a metallurgist here on the list.

Again I'm not sure but I believe in certain applications like knife making
the steel is has less nickel and chromium to ensure that the blade is "soft"
enough to take an edge. So the bottom line (as I understand it)is that some
stainless is more corrosion resistant than others.

Cheers,
