Is 316 stainless steel food grade?
 
316 stainless is very well suited to food applications.  The reason you won't
see it very often in honey equipment is that 316 stainless is more expensive
than 304 stainless (which also works well in most food applications).   The
food application where I would specify 316 stainless would be one with a lot
of salt (example: pickling solutions).
 
FYI:  316 stainless is now the material of choice for reactor coolant system
piping in nuclear power plants.  304 stainless gave trouble.
