ABSTRACT:
A slurry of ferrosilicon powder is applied to both sides of a low carbon steel strip. The particle size of the ferrosilicon powder is controlled so that, after the slurry coatings are dried, there exists on each side of the steel strip at least a single layer of closely packed particles. The coated strip is then compacted. It is next heated in a protective environment to cause uniform diffusion of silicon throughout the strip.
