Stainless doesn't need to rust, when it is so easily attacked by
chlorides, and it will, in fact, rust.


Not only rust. It dissolves.

Our previous house had a pool. I was working on the filter for it one day
and took it apart for cleaning. The filter section had been held in place
by several stainless steel bolts. The only thing left on them were the
heads. The threaded sections had been completely eaten away by the chlorine
in the pool water.
