Abstract
Provided are a steel sheet for a can having high buckling strength for a can body against an external force and excellent formability when being formed into a shape having a design effect by additionally giving elongation strain in the circumferential direction after the steel sheet having been formed into a cylindrical shape and a method for manufacturing the steel sheet. The chemical composition is controlled to contain, by mass %, C: 0.0005% or more and 0.0035% or less, Si: 0.050% or less, Mn: more than 0.60% and 1.00% or less, P: 0.030% or less, S: 0.020% or less, Al: 0.010% or more and 0.100% or less, N: 0.0030% or less, B: 0.0005% or more, and the balance being Fe and inevitable impurities, in which the relationship B/N≥0.50 is satisfied where B/N represents (B(mass %)/10.81)/(N(mass %)/14.01), and a Young's modulus in a direction at an angle of 90° to the rolling direction is 220 GPa or more.
