Do magnets stick to stainless steel?

Magnets generally do stick to stainless steel, though exceptions to the rule can be found. Steel is composed mostly of iron, which is often naturally magnetic and can easily be magnetized. Magnetic stainless steel is usually ferritic, with a high iron content and molecular structure that supports a magnetic field.

Some stainless steel, however, is classed as austenitic. These alloys have a distinct molecular structure that interferes with the parallel lines of force needed for a strong magnetic field. Austenitic stainless steel is commonly used for industrial, chemical and food-handling applications. Ferritic stainless steel is common in home appliances such as refrigerators.
