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 825 excel files on magnetic properties of all NGO steels. Of these, 274 files contain B(H) Curves and Permeability Curves plus Saturation Flux Density, Resistivity, Annealing etc if available. Balance 116 files contain Core Loss Curves.
By downloading, you will have 825 files of magnetic properties of all NGO electrical steels produced world wide at your finger-tips ! Please review the MagWeb Database for a complete listing of all the NGO steels in this folder.
