Conventional grain-oriented electrical steel, commonly called conventional CRGO or grain-oriented silicon steel, is used in transformer cores requiring consistent magnetic properties and controlled material cost. It is suitable for laminated and wound core production when the grade, thickness and processing route are properly matched to the transformer design.
