ABSTRACT:
In the production of non-oriented electrical steel sheets, it has been attempted to decrease the watt loss, e.g., by adding Sn to silicon steels, but in such a case the relationship between the watt loss and the magnetic flux density falls within the curves 1 and 1' in FIG. 1. The addition of boron is therefore unsatisfactory for meeting the recent demand for improving the magnetic properties of a non-oriented electrical steel sheet over those indicated by the curve 3.
In the present invention, the combined addition of Sn and B and/or sol. Al results in the development of (110) and (100) textures, which are desirable for the magnetic properties.
A non-oriented electrical steel sheet according to the present invention consists of:
