Provided are a steel sheet for a can and a manufacturing process therefor. This steel sheet ensures high bucking strength of a can body against external force, and exhibits excellent workability in working the steel sheet even into a shape having design characteristics. The excellent workability is achieved by forming the steel sheet into a cylinder and thereafter imparting a circumferential tensile strain to the cylinder. The steel sheet has a composition which contains, in mass%, 0.0005 to 0.0035% of C, at most 0.050% of Si, more than 0.60 to 1.00% of Mn, at most 0.030% of P, at most 0.020% of S, 0.010 to 0.100% of Al, at most 0.0030% of N, and at least 0.0005% of B with the balance being Fe and unavoidable impurities and which satisfies the relationship: B/N = 0.50 [wherein B/N represents (B(mass%)/10.81)/(N(mass%)/14.01)], while the Young's modulus of the steel sheet in the direction at 90º to the rolling direction is 220GPa or more. |
