Some grades of stainless steel aren't magnetic. Depends on how much
nickel is in it, I gather.
No, how much chromium. Low chromium makes it magnetic.

No, back atcha! Unlike humans, steel that's got the hots is
non-magnetic. Nickel makes the non-magnetic state stable at low
temperatures. This is shown in the quote below. If chromium also
has this property, it's probably less effective than nickel. The
same web page notes that to increase the corrosion resistance of
steel, chromium is added.

Gosh! With all this metallurgical discussion in a photography group
you'd think the P&S guy would jump in to chastise us "resident-trolls"
for our off-topic posts.

At least RichA doesn't have an excuse for an anti-plastic rant.
