<P>PROBLEM TO BE SOLVED: To provide a magnetic stainless steel sheet which has reduced core loss even when used in a high-frequency region. <P>SOLUTION: This magnetic stainless steel is a rolled steel sheet with a thickness of 0.02 to 0.6 mm containing, by mass, 5 to 20% Cr, 0.01 to <2.5% Si and 0.1 to 7.0% Al, and the balance substantially Fe. The steel sheet exhibits a value of ≥5% in elongation after hot rolling, and has an electric resistivity of ≥0.6 μΩm, and also, a core loss when measured at a frequency of 20 kHz and a magnetic flux density of 0.1 T is ≤800 kW/m<SP>3</SP>. <P>COPYRIGHT: (C)2004,JPO |
