Electrical steels are steels enhanced with magnetic properties through their %Si content.
Shaping the Future: High-Quality Electrical Steel and Innovative Solutions from Europe to the World
Electrical steels are a type of steel with high %Si content and the most important feature is their low magnetic loss compared to standard steels.
Main scope of electrical steel is to create best conductivity of magnetic field which assures the minimum loss in energy transformation. They are generally produced in cold rolled strips less than 1 mm thickness.
Electrical steels are divided into NGO (Non Grain Oriented) and GO (Grain Oriented) grades according to the magnetic behavior. Only fully processed NGO grades are produced in Erdemir Romania plant.
NGO grades are produced according to EN 10106 standard and have Si content ranging between 0.6-3.0%. Grains are oriented independently from the rolling direction and the magnetic property of the material remains same in all directions. 0.35 - 0.50 - 0.65 and 1.00 mm thicknesses are available.
NO Grades are special type of NGO electrical steels with improved properties at medium frequencies specially dedicated to e-mobility.
