Chrome Moly steel vs. Stainless steel

["atrav" <atrav@copper.net>]

Is there an easy way to tell the difference between chrome moly steel and 
stainless?
I was told today that a magnet won't stick to chrome moly either, so...

What has happened is I think my machinist goofed up, not only measurements, but 
material as well.
These are some little spacers, fresh off of the lathe, so hard to tell.
