Els acers elèctrics no orientats presenten propietats magnètiques uniformes en la direcció de laminació i altres direccions. S'utilitzen àmpliament per als materials del nucli de ferro de les màquines rotatives, des dels generadors d'energia de grans dimensions fins als motors elèctrics de precisió de mida petita. També són desitjables per als nuclis de ferro dels transformadors de potència de mida petita.
