Abstract
A steel sheet exhibiting good drawability and excellent buckling strength of a can body portion against an external pressure, and a method for manufacturing the same. The steel sheet includes C: 0.0030% or more and 0.0100% or less, Si: 0.05% or less, Mn: 0.10% or more and 1.0% or less, P: 0.030% or less, S: 0.020% or less, Al: 0.010% or more and 0.100% or less, N: 0.0050% or less, Nb: 0.010% or more and 0.050% or less, and incidental impurities. Contents of C and Nb satisfy 0.10≤([Nb]/92.9)/([C]/12)<0.60, the HR30T hardness of the steel sheet is 56 or more, and the average Young's modulus of the steel sheet is 210 GPa or more.
