grain-oriented electrical steel, grain-oriented sheet, grain-oriented silicon steel, oriented silicon steel
steel alloyed with silicon that is anisotropic in that it possesses a metallurgical structure that gives preferential magnetic properties in the direction of rolling (see: electrical steel; compare: non-oriented grain electrical steel), räniga legeeritud teras, mis on anisotroopne, kuna selle metallurgiline struktuur tagab valtsimissuunas eelistatud magnetilised omadused (vt elektrotehniline teras; vrd mitteteraorienteeritud elektrotehniline teras)
