Why does a magnet stick to Frigidaire Stainless Steel?

Like steel, stainless steels are relatively poor conductors of electricity, with significantly lower electrical conductivity than copper. Ferritic and martensitic stainless steels are magnetic. Annealed austenitic stainless steels are non-magnetic. Work hardening can make austenitic stainless steels slightly magnetic.

Induction Cookers require electromagnetic iron or steel to work. That means that if you bring a magnet near the metal side in contact with the induction spiral then it is magnetic. Get a magnet and see if it sticks to the metal. If it does then it is magnetic and will induce eddy currents to heat up the metal from the oscillating magnetic field. Aluminium won't work and neither will most stainless steel. I likes raw steel, say like a wok pot for example or pots made specifically for induction cooking.

magnets dont stick to gold

Most cookware found found in home today is aluminum or cast aluminum. These do not work on induction cook tops. Even older stainless steel Farberware doesn't work because it is not magnetic. Look for an induction compatible label or stamp on the cookware to be sure.
Induction cookware must be made of a magnetic-based material, such as cast iron or magnetic stainless steel. Fully clad cookware brands, such as All-Clad Stainless, Le Creuset Stainless Steel and Mauviel M'cooks stainless work on induction cooktops because they're magnetic.

It is commonly stated that "stainless steel is non-magnetic". This is not strictly true and the real situation is rather more complicated. The degree of magnetic response ormagnetic permeabilityis derived from the microstructure of the steel. A totally non-magnetic material has a relative magnetic permeability of 1. Austenitic structures are totally non-magnetic and so a 100% austenitic stainless steel would have a permeability of 1. In practice this is not achieved. There is always a small amount of ferrite and/or martensite in the steel and so permeability values are always above 1. Typical values for standard austenitic stainless steels can be in the order of 1.05 - 1.1. SeeComposition effects on the magnetic permeability of austenitic stainless steels
It is possible for the magnetic permeability of austenitic steels to be changed during processing. For example,cold work and weldingare liable to increase the amount of martensite and ferrite respectively in the steel. A familiar example is in a stainless steel sink where the flat drainer has little magnetic response whereas the pressed bowl has a higher response due to the formation of martensite particularly in the corners.
In practical terms, austenitic stainless steels are used for "non-magnetic" applications, for example magnetic resonance imaging (MRI). In these cases, it is often necessary to agree a maximum magnetic permeability between customer and supplier. It can be as low as 1.004.

The fridge freezers are called stainless steel but it is a term that is used more for marketing than an actual statement of what they are made of, the grade of stainless steel they use is very very low grade and the manufacturers of the appliances coat the steel with a protective clear coat to stop corrosion. This is why it is magnetic.

Stainless steel is a term for a family of high chromium steels, some of which do in fact stain, although they do not rust as ordinary steel does.

The more expensive 'austenitic' stainless is non-magnetic, but harder to work into product shapes. 'Martensitic' stainless is a little more prone to staining and corrosion, but easier to work with, and is magnetic. Then 'ferritic' stainless is even cheaper, but less corrosion proof, and is also magnetic.

So yes, many stainless steels are magnetic, and if the manufacturer has not used the very most corrosion proof but expensive grade, then you will see it in that way. I would not see much reason for a fridge door to be made from austenitic stainless.

Normally these appliances use brushed steel which gives a stainless steel look.

Get a magnet and run it on the sheet. If it sticks then it definitely is not stainless steel.
However, with wear and tear stainless steel surface does break down causing rust to start.

> Refrigerator was sold as 'stainless steel', but is not, a magnet won't stick to it.
There are many different alloys that are called 'stainless' steel but all of them have some chrome, some nickel and some steel. Depending on the strength of the magnet and the specific alloy, it may or may not adhere. Generally, the higher chrome and nickel content, the less magnetic it will be.
I think that the brushed surface of your fridge was coated with a kind of clear-coat to prevent fingerprints from adhereing to the brushed surface and that clear-coat is now missing in the areas of concern.
The only cure for tha would be the wholesale removal of the doors and the remaining clear finish and then respraying it with a quality clear finsh.
Ain't progress grand?
We considered all stainless stuff for our new home a couple of years ago, decided we liked black better and now hate that too.     

This model does not list Stainless Steel as a feature. Stainless Steel is used in the interior (CAVITY) of a Microwave if it is a Combination Convection/Microwave Oven. The Convection Oven can reach temperatures of 400+ degreesF. This Temperature would MELT the paint off a painted interior.
Stainless Steel can be tested with a Magnet. It will not be attracted or "Stick" to Stainless.
Hope this answers your concerns!
Thanks!
