All stainless steel contains varying amounts of iron, carbon, and corrosion-inhibiting chromium. However, ferritic stainless steel, often used for induction cookers, contains a higher percentage of chromium (at least 10.5%) than does austenitic stainless steel as well as a higher concentration of iron. Unlike ferritic stainless steel, austenitic stainless steel has a face-centered cubic crystalline structure held stable by the presence of nickel and nitrogen. Austenitic stainless steel has two subtypes: the 200 series, often used for washing machines, and the 300 series, which has more nickel than the 200 series and is often used for storage containers or furnaces. Thus, stainless steel used to manufacture

furnaces and stainless steel used to manufacture washing machines will both have a chromium content of less than 10.5%.

washing machines will have a higher concentration of nickel in its composition than stainless steel used to manufacture furnaces will.

induction cookers will have a face-centered cubic crystalline structure, but stainless steel used to manufacture storage containers will not.

storage containers and stainless steel used to manufacture induction cookers will have a similar concentration of nitrogen in their compositions.
