STEEL SHEET FOR CANS AND MANUFACTURING METHOD THEREOF

摘要

This steel sheet for cans contains, in mass%, C: 0.0030% or less, Si: 0.02% or less, Mn: 0.05%-0.60%, P: 0.020% or less, S: 0.020% or less, Al: 0.010%-0.100%, N: 0.0010%-0.0050% and Nb: 0.001%-0.050%, the remainder being Fe and unavoidable impurities. It holds that (integrated intensity of (111)[1-21] orientation)/(integrated intensity of (111)[1-10] orientation) ? 0.9, and in the rolling direction and the direction 90° from the rolling direction in the horizontal plane, it holds that the tensile strength TS ? 550 and the elongation at break E1 > -0.02×TS+17.5.
