If iron cobalt and nickel are magnetic (which I think is the right term, but it feels wrong since magnets stick but it doesn’t magnet to other steel) then why does using nickel to make stainless steel render steel non-magnetic?
Or is my metallurgical understanding just completely off?
In: Physics
Not all iron is magnetic. Austenite, which is a type of iron with a specific arrangement of atoms (specifically, a face-centered cubic unit cell) is non-magnetic.
Ferrite iron, which is magnetic, can transition to austenite at high temperatures – such as those used to make steel.
