<P>PROBLEM TO BE SOLVED: To provide a high-strength high-workability steel sheet for a can having tensile strength of 550 MPa or more and elongation at break of 7% or more. <P>SOLUTION: The high-strength high-workability steel sheet for a can includes, in mass%, 0.001-0.080% of C, 0.003-0.100% of Si, 0.10-0.80% of Mn, 0.001-0.100% of P, 0.001-0.020% of S, 0.005-0.100% of Al, more than 0.0150% and 0.0200% or less of N, and 0.0002-0.0050% of B, with the balance comprising Fe and unavoidable impurities, and further has a content of N which exists as AlN of 0.0060% or less, and an average crystal grain size of 5.00 μm or more and an elongation rate of a crystal grain of 3.00 or less in a cross-sectional surface in the rolling direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
