STEEL SHEET FOR CANS AND MANUFACTURING METHOD THEREOF

摘要

A can steel plate includes: equal to or less than 0.0030% by mass of C; equal to or less than 0.02% by mass of Si; 0.05% to 0.60% by mass of Mn; equal to or less than 0.020% by mass of P; equal to or less than 0.020% by mass of S; 0.010% to 0.100% by mass of Al; 0.0010% to 0.0050% by mass of N; 0.001% to 0.050% by mass of Nb; and balance Fe and inevitable impurities, where (intensity of (111) [1-21] orientation)/(intensity of (111)[1-10] orientation) ‰¥ 0.9, in a rolling direction and a 90° direction from the rolling direction in a horizontal plane, tensile strength TS ‰¥ 550, and fracture elongation El > -0.02 x TS + 17.5.
