Why do magnets stick to my stainless steel fridge?

Why Do Magnets Stick to Some Stainless Steel Appliances? If the stainless steel skin of an appliance is relatively thin and the underlying core is ferromagnetic, a strong magnet will cling to the surface because the magnetic force penetrates through the stainless steel to the underlying material.

Which stainless steel is not magnetic?

However, the most common stainless steels are ‘austenitic’ – these have a higher chromium content and nickel is also added. It is the nickel which modifies the physical structure of the steel and makes it theoretically non-magnetic. 304 stainless steel contains chromium (min.

How can I tell if my stainless steel is 304 or 316?

Try the magnet test. If the magnet sticks it cannot be 316 and might be 304. If the magnet doesn’t stick it could be either 316 or cold worked 304, so heat the piece to about 800 °C, let air-cool and try again with magnet. If it sticks now its 304 SST.
