Abstract
The present invention relates to a soft high-silicon steel sheet, and more particularly, to a soft high-silicon steel sheet which has ductility even if the silicon content thereof is greater than 4%, and can thus be manufactured into a steel sheet having a high silicon content only by means of rolling without an additional siliconizing process. The soft high-silicon steel sheet may include a silicon content greater than 4 wt % and less than or equal to 7 wt % and 1 to 20% of chromium, or may include 5 to 7 wt % of Si+Al and 1 to 20 wt % of chromium.
