I would bet it’s steel plated with zinc, (much cheaper than quality
stainless steel) and if I remember right when heated it gives off
toxic fumes, much less eating it. But google it first. It’s best to
be prepared before you complain. If you can take a counter to a
plating company and say “Here’s $25 bucks what is this?” Hopefully
the guy won’t say “You don’t eat off this thing do you?” 
Just an idea.
