<p><P>PROBLEM TO BE SOLVED: To provide a steel sheet for a thin-walled deeply drawn can excellent in pressure-resistant strength. <P>SOLUTION: The steel sheet for the thin-walled deeply drawn can is a cold-rolled steel sheet, of which the steel component comprises 0.01-0.06 mass% of C, 0.1-0.6 mass% of Mn, 0.01-0.10 mass% of Al, 0.0010-0.0050 mass% of N and the remainder of Fe and inevitable impurities and is characterized in that a content raito Al/N of Al and N on a mass% basis is 25 or below, and which is subjected to cold rolling twice and has an organic resin film laminated thereto under heating. The rising quantity of tensile strength of this steel sheet, after processing of a corresponding strain of 0.2 and heating at 210°C for 3 min are performed in this order, is 80 MPa or above. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
