How to tell magnetic stainless?
Awl--
I suppose it's not quite as magnetic as plain carbon steel.
And perhaps a spark test? Characteristics?
Oh, I guess you could use the O/A test: it don't cut!! But that's pita...
I've heard of machinists/heat treaters who have "catalogued" hundreds of
alloys merely by the spart test on a grinding wheel--keep a box w/ reference
samples. wow...
