Abstract

Provided is a steel sheet for a can, which has high strength and excellent ductility, and also exhibits uniform deformability and excellent workability. This steel sheet has a constituent composition that contains, in terms of mass pcnt , 0.020-0.130 pcnt of C, not more than 0.04 pcnt of Si, 0.10-1.20 pcnt of Mn, 0.007-0.100 pcnt of P, not more than 0.030 pcnt of S, 0.001-0.100 pcnt of Al, more than 0.0120 pcnt and not more than 0.0200 pcnt of N, 0.0060-0.0300 pcnt of Nb and not more than 0.040 pcnt of Cr, with the remainder comprising Fe and unavoidable impurities. The ratio of the content of Nb in precipitates having diameters of less than 20 nm relative to the content of Nb in all precipitates is at least 40 pcnt . The average interval between all precipitates is not more than 30 nm. The upper yield strength is 500-640 MPa and the total elongation is at least 10 pcnt following a heat treatment at 210§C for 10 minutes.
