Abstract

The present disclosure provides a non-grain-oriented electrical steel strip which can be used in electric machines such as electric motors and generators. In examples, the non-grain oriented electrical steel strip can be used as a stator having good magnetic properties and as a rotor having good mechanical properties. A reference heat treatment performed subsequent to an initial final heat treatment makes it possible to obtain improved magnetic properties.
