Stainless steel possesses a lower magnetic permeability value compared to ordinary steel bars. Rebar with appreciable magnetic permeability can create its own magnetic field when subjected to an external magnetic field. But in the case of stainless steel, the external magnetic field does not influence its magnetic field to a great extent, thus maintaining its strength and toughness. The lower magnetic permeability value of stainless steel is hence used in the application of deperming stations.
