Electrical Steels are ultra low carbon steels (with <4% Silicon to reduce core losses). The Non-Grain Oriented (NGO) type electrical steels are those with near-isotropic properties. They are lower in cost, but produce higher core losses. They are used mostly in Electric Motors. Their properties are sensitive to trace impurities, which differ from manufacturer to manufacturer. So MagWeb lists the properties of these steels by each manufacturer, irrespective of their grade.
This zipped folder contains 1223 excel files on magnetic properties of all NGO steels. Of these, 634 files contain B(H) Curves and Permeability Curves plus Saturation Flux Density, Resistivity, Annealing etc if available. Balance 589 files contain Core Loss Curves.
Version 5 also added a DIGEST, which lists properties of all these materials at a single point in a single excel file.
By downloading, you will have 1223 files of magnetic properties of all NGO electrical steels produced world wide at your finger-tips ! Please review the List of Materials for a complete listing of all the NGO steels in this folder.
For more technical info on magnetic properties of NGO steels, please download the Handbook.
