Ray,
That's interesting!
304 may be magnetic?
That's cool!

  It may well be that the Cushcraft stainless steel is of a different
composition
than what we're used to. There's 3 or 4 versions, it depends on the amount
of nickel and chromium in the mixture. There is one version of stainless, I
think 304, that is still magnetizing, that is you bring a magnet up to to
and
it's attracted to it. I think there's also a 306, a 307, and a 312.
