Magnetisim is not a test of whether something is made from stainless or
There are probably 20 or so common alloys of stainless, with another
20-50 uncommon ones.
Of these, a couple are pretty much nonmagnetic- 316 is pretty reliably
Many others, while still considered "stainless steel" are magnetic to
Most common stainless is 304. This is relatively nonmagnetic as rolled,
but if cold worked much, gets more magnetic. Also, if forged, it can
get more magnetic.
So if it is rolled to a thinner gage, then bent or punched or rolled,
chances are it will be magnetic, although less so than mild steel is.
I cook a lot of oysters on my grill, so I have replaced the burners,
heat diffuser, lava rock tray, and grates with all stainless material.
