If iron is magnetic and nickel is magnetic, why isn’t stainless steel?

577 viewsOtherPhysics

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?

*Some* stainless steel is magnetic! Of the five most common types of stainless steel, *austenitic* stainless steel is generally not magnetic, and this lack of magnetism is due to its crystal structure more than the elements that make it up — how the atoms are arranged in the metal.
