  • Grain oriented electrical steel with improved forsterite coating characteristics
    Patent number: 11942247
    Abstract: Increasing the chromium content of an electrical steel substrate to a level greater than or equal to about 0.45 weight percent (wt %) produced a much improved forsterite coating having superior and more uniform coloration, thickness and adhesion. Moreover, the so-formed forsterite coating provides greater tension potentially reducing the relative importance of any secondary coating.
    Type: Grant
    Filed: December 21, 2017
    Date of Patent: March 26, 2024
    Assignee: Cleveland-Cliffs Steel Properties Inc.
    Inventors: Jerry William Schoen, Kimani Tirawa Partin, Christopher Mark Wilkins
