Steel sheet for cans and method for manufacturing the same

Abstract

A steel sheet for cans has a chemical composition containing, in mass percent, C: 0.085% to 0.130%, Si: 0.04% or less, Mn: 0.10% to 0.60%, P: 0.02% or less, S: more than 0.010% to 0.020%, Al: 0.02% to 0.10%, N: 0.0005% to 0.0040%, Nb: 0.007% to 0.030%, and B: 0.0010% to 0.0050%, B/N that is the ratio of the content (mass percent) of B to the content (mass percent) of N being 0.80 or more, the remainder being Fe and inevitable impurities, and a ferrite microstructure containing 1.0% or more pearlite in terms of area fraction. The steel sheet for cans has a yield stress of 500 MPa or more, a tensile strength of 550 MPa or more, a uniform elongation of 10% or more, and a yield elongation of 5.0% or less.
