EVALUATION OF MICROSTRUCTURAL CHANGES OF S235 STEEL AFTER ROLLING ON THE BASIS OF MICROSCOPIC OBSERVATIONS AND EDDY CURRENT NON-DESTRUCTIVE magnetic permeability caused by deformation. after removing of 0.2 mm of material thickness (W cross section). The orientation maps were prepared. The results are shown on figures 7 and 8. Magnetic Test Method Magnetic Thickness Measurement The magnetic permeability indicates how well a material adapts to a magnetic field. Substances such as iron or nickel have high permeability. They become magnetized themselves and strengthen the magnetic field. Since the permeability is different for the metals and their alloys, the measuring device has to be recalibrated when the materials change. Magnetismw.wang 47 Permeability is defines as µ= (1+) µ= µr µ Whereµr is relative permeability. is susceptibility. Typical values for ordinary liquids and solids are in the range µr = 1.00001 to 1.003. µr = 1 when the material does not respond to the magnetic field by magnetizing. µr > 1 implies material magnetizes in response to the applied magnetic field.
Permeability TRAN-COR H-1 Oriented TRAN-COR H-0 DR TRAN-COR H-1 DR Grade Designations The American Iron and Steel Institute type numbers and AK Steel designations for electrical steel grades con-sist of the letter M followed by a number. The M stands for magnetic material; the number is representative of the core loss of that grade. Shielding Materials - K&J MagneticsLow carbon steels have a Permeability of 1000 - 3000, while MuMetal can have values as high as 300,000 - 400,000. The saturation point is the flux density at which the material can not contain any more magnetic flux. Steel saturates around 22,000 Gauss, while MuMetal saturates at about 8,000 Gauss. Structural Steels S235, S275, S355, S420 and Their PropertiesIn S235 steels case, this value is 235 MPa. Anything below results in elastic deformation, meaning that your detail will regain its former shape after removing the load. Tensile strength refers to the maximum load that does not break the metal. Continuing with the S235 example, this value is
