  1. Magnetic Properties of Stainless Steel

    The best austenitic stainless steel types for low permeability applications are those with high austenite stability as these have low permeability in both annealed or cold worked conditions. These include the nitrogen bearing types, 304LN (1.4311) and 316LN (1.4406) or the high nickel types such as 310 (1.4845).

  2. Permeability - Engineering ToolBox

    = permeability of the medium (H/m) The lowest relative magnetic permeability of a paramagnetic material is 1.0 - and the magnetic response of the material is the same as 'free space' or complete vacuum. 1) Permeability of austenitic stainless steels is not like ferritic, martensitic and duplex stainless steel.

  3. Permeability (electromagnetism) - Wikipedia

    The reciprocal of magnetic permeability is magnetic reluctivity. In SI units, permeability is measured in henries per meter (H/m), or equivalently in newtons per ampere squared (NA 2 ). The permeability constant 0 , also known as the magnetic constant or the permeability of free space, is a measure of the amount of resistance encountered when forming a magnetic field in a classical vacuum .

    Type Analysis of Stainless Steel. Transformation from non-magnetic to magnetic phases. As both 316 and 304 stainless steels are austenitic, when they cool, the iron remains in the form of austenite (gamma iron), a phase of iron which is nonmagnetic. The different phases of solid iron correspond to different crystal structures.

    Magnetic Permeability Magnetic permeability is the ability of a material to carry magnetism, indicated by the degree to which it is attracted to a magnet. Grade 316 has very low magnetic properties and shows almost no response to a magnet after cold working, while 18-8 grades (302, 303, 304) exhibit quite a strong response to a magnet (see Fig. 1).

  7. 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.

  8. Magnetic Permeability: Why Are Some Materials ... - Dura Mag

    A materials permeability indicates how easily an external magnetic field can induce an internal field in the material. The higher the internal field, the higher the force of attraction. A materials permeability is not constant and changes based on number a of factors. The effective permeability of a material can change with the temperature, how it was processed, the intensity of the applied drive field, humidity, etc.

    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.

  10. Magnetism in Stainless Steel Fasteners | Fastenal

    Type 304 is an example of a stainless steel that is quite susceptible to forming martensite after cold working but in fact MSIT affects all austenitic stainless steel to some degree or another. To help showcase these differences Figures 1 & 2 have been provided to show permeability (magnetism) vs. percent cold working as well as magnetism vs. tensile strength of some common stainless steels.
