Oriented Electrical Steels
Oriented electrical steels are iron-silicon alloys that were developed to provide the low core loss and high permeability required for more efficient and economical electrical transformers. Available in grades M-2, M-3, M-4 and M-6, with superior magnetic properties in the rolling direction, oriented steels are used in transformer cores. They are used in large generators and other apparatus when the design permits the directional magnetic characteristics to be used efficiently. The AK Steel Technology Center continues to develop new and improved grades to provide the electrical industry with core materials for the manufacture of more efficient electrical apparatus.
