PROBLEM TO BE SOLVED: To provide a nonoriented silicon steel sheet for high frequency reactor, having particularly excellent magnetic properties in a frequency region of >=1 kHz. SOLUTION: This steel sheet has a composition which consists of, by mass, 2.5-10% Si, 1.5-20 mass % Cr and the balance Fe with inevitable impurities and in which the contents of C and N among the inevitable impurities are controlled to <=0.005 mass %, respectively, and also the content of at least either one of Ti and Nb is controlled to <=0.005 mass % is. |
