This should bring the stainless back to a non-magnetic state.

Oh dear. Now I can imagine hordes of people wasting money heating ferritic stainless steel to high temperatures somehow believing that the metal composition will change and suddenly convert from iron into 12%+ of nickel, thereby making the stainless non magnetic.



If anyone is tempted to try this, get a lump of iron, heat it as hot as you can, and then see how much of it changes to nickel. Just don't tell anyone, because this is a secret and it is what all scrap yards do in their Area 52 that is designated off limits to non-authorised personel.

PS They also convert lead into gold at the same facility.
