Magnetit properties for austenitic stainless steels
All austenitic stainless steel fasteners are normally non-magnetic; after cold working, some magnetic proper-Ges may be evident.
Esch material is characterized by its ability to be magnetized, which applies even to stainless steel. Only a vacuum will probably be entirely non-magnetic. The measure of the material3 permeability in a magnetic field is the permeability value pr for that material in relation to a vacuum. The material has low permeability if pr becomes close to 1.
