Karla was our first featured CMSR Cook in our monthly newsletter and on our home page. She is a culinary student in Toronto. Karla purchased a sheet of Stainless Steel at a local DIY store. She adhered the magnetic strip to the bottom of each of her Elegance Squares. She tells us she is the envy of her fellow culinary students.
Not all Stainless Steel is Magnetic!
Stainless steel is the universal name for a number of different steels used primarily for their anti-corrosive element. When it comes to classifying stainless steel as having magneticmagneticmagnetic properties, there is not a simple yes and no answer.
It is important to understand that stainless steel is not a pure magnetic metal. In fact, stainless steel is really a collective name for a steel alloy that is mixed with other metals in order to give it the properties that make the metal compound so desirable. For instance, the typical stainless steel contains just over ten percent of chromium. Other metals may be introduced into the steel compound as well as the chromium. One of these metals is nickel. Essentially, the addition of nickel to the stainless steel compound helps to strengthen the protective qualities of the chromium. Generally referred to as a 300 series, stainless steel that contains nickel is not magnetic at all. The reason is that the presence of the nickel alters the physical structure of the stainless steel and removes or inhibits any magnetic qualities. Stainless steel refrigerators are not magnetically attractive.
However, magnetic stainless steel does exist. The 400 series, which contains steel and chromium, but without the presence of nickel, does have magnetic qualities. The degree of magnetic attraction may vary. Because the Grade (300, 400, etc. ) may not be displayed at your DIY store, it is recommended to take a magnet or one of your tins with the magnetic material on the bottom with you to test for magnetic attraction.
