Patent ID: 7534312

Claim:
A steel sheet excellent in workability, comprising: steel including, in mass, 0.11 to 0.25% C, 0.001 to 1.5% Si, 0.01 to 2.0% Mn, 0.001 to 0.04% P, at most 0.05% S, 0.001 to 0.007% N, and 0.008 to 0.2% Al; the steel sheet having an increased texture of the {110} orientation resulting in the steel sheet having an average r-value of at least 1.2, an r-value in the rolling direction (rL) of at least 1.3; an r-value in the direction of 45 degrees to the rolling direction (rD) of at least 0.9, and an r-value in the direction of a right angle to the rolling direction (rC) of at least 1.2, wherein the steel sheet having ratios of X-ray diffraction intensities in the orientation components of {111}, {100} and {101} to random X-ray diffraction intensities on a reflection plane at the thickness center of said steel sheet are at least 2.0, at most 1.0 and exceeds 0.2, respectively.
