Abstract:
A can steel plate includes: equal or less than 0.0030% by mass of C; equal or less than 0.02% by mass of Si; 0.05-0.60% by mass of Mn; equal or less than 0.020% by mass of P; equal or less than 0.020% by mass of S; 0.010% to 0.100% by mass of Al; 0.0010-0.0050% by mass of N; 0.001-0.050% by mass of Nb; and balance Fe and impurities. Intensity of (111) [1-21] orientation (where −2 represents 2 with bar in Miller indices) and intensity of (111)[1-10] orientation (where −1 represents 1 with bar in Miller indices) satisfy the following equation (1), and in a rolling direction and 90° direction from the rolling direction in a horizontal plane, tensile strength TS (MPa) and fracture elongation El (%) satisfy relations of the following equations (2) and (3). (Intensity of (111) [1-21] orientation)/(Intensity of (111) [1-10] orientation)>0.9 . . . (1), TS>550 . . . (2), El>−0.02×TS+17.5 . . . (3).
