<P>PROBLEM TO BE SOLVED: To provide a steel sheet excellent in press formability and magnetic properties, and to provide its production method. <P>SOLUTION: The steel sheet has a composition containing, by mass, ≤0.005% C, ≤0.1% Si, 0.1 to 0.5% Mn, ≤0.1% P, ≤0.01% S, ≤0.004% sol.Al, ≤0.005% N and ≤0.02% O, and the balance Fe with inevitable impurities, and having the average crystal grain size of ≥40 μm, and in which the X-ray diffraction intensity in the (222) crystal face parallel to the steel sheet face is ≥8 times the X-ray diffraction intensity in the (222) crystal face of a standard random sample. <P>COPYRIGHT: (C)2008,JPO&INPIT |
