richard,
You are so right, although its embedded iron from post working that is the
real culprit in Stainless Steel corrosion. If site corrosion is a big
concern (unless youve got water injection running on your dak (link) it
shouldnt be) then a passivation treatment will remove the iron and develop
an oxide layer (the basic mechanisim behind the corrosion resistance of
stainless steel) to prevent discoloration. Therefor every one is basically
right since its the layer of oxide that keeps things from disappearing into
thin air!

Not! Stainless steel is an Alloy with mostly steel and some chromium I
think.
Some lower grades of stainless do rust (just much slower than steel).

However, the surface rusting phenomonon associated with sanding or grinding
on
stainless is usually due to using a grinding wheel or sandpaper that has
been
previously used on carbon steel. The steel particles become embedded in the
stainless surface. They then rust and it appears as if the stainless is
rusting.
