  9. Stainless Steel - Magnetic Properties

    Magnetic permeability is a property of a material that responds to magnetism. It is usually represented based on the extent to which a magnet attracts the material. Except austenitic grades, all types of stainless steels strongly respond to a magnetic field. Austenitic stainless steel grades exhibit ss 420j1 magnetic permeability

  10. Permeability (electromagnetism) - Wikipedia

    A good magnetic core material must have high permeability. For passive magnetic levitation a relative permeability below 1 is needed (corresponding to a negative susceptibility). Permeability varies with a magnetic field. Values shown above are approximate and valid only at the magnetic fields shown.

    Selecting a 316 stainless steel with nickel content that is in the upper side of the allowed content range may also be helpful, but again, may not always be practical. The 316N stainless steel alloy is expected to have less of a tendency to become magnetic than 316 or 316L, however, it may not be readily available.
