Magnetic properties of austenitic stainless steel (standards: ISO 3506, GB/T3098.6) All austenitic stainless steel fasteners are usually non-magnetic; After cold processing, some magnetism may become apparent. The magnetization ability of various materials is also applicable to stainless steel. It is only possible to be completely non-magnetic in a vacuum state. The measurement of the magnetic permeability of materials in a magnetic field is equivalent to the magnetic permeability μ r of materials in vacuum. If μ r is close to 1, the material has low magnetic permeability. For example: A2:μr≈1.8 A4:μr≈1.015 A4L:μr≈1.005 F1:μr≈5 The strength of magnetism is closely related to the alloy composition of steel: Magnetic formula: MD30=551-462x (C+N) -9.2xSi-8.1xMn-13.7xCr-29x (Ni+Cu) -18.5xMo. The smaller the value, the smaller the magnetic properties.
