Magnets do not stick to stainless steel refrigerators. This applies to refrigerators that are made of high grade stainless steel.
Some people face the problem of rusting refrigerators. If the refrigerators are made of high grade stainless steel, they should not rust. The reason for the corrosion is due to the use of low grade stainless steel. Nickel, which is a component of high grade stainless steel prevents rust. But, due to nickel's price increase some years ago, some refrigerator manufacturers use stainless steel that does not contain nickel to cut down on operational costs. A good way to find out if the refrigerator to be purchased is truly made of high grade stainless steel is to stick a magnet to it and see the result.
