[TowerTalk] Why galvanized crank up cables instead of stainless?

[Richard (Rick) Karlquist]

Having just replaced my crank up cables (in case they might
be rusted internally), I am wondering why stainless steel
cables aren't used.  It would seem that they would avoid
the latent rust issue.  I realize that they are not as strong,
but they could simply be sized appropriately.  Is it the
case that they may still rust, just more slowly?  Would
they somehow wear out and break internally?  It would be
great to merely have to inspect the cables for obvious broken
strands and never have to replace them on a preventative basis.
Can someone explain this?  Don't airplanes use SS cables?
