罐用钢板及其制造方法
摘要：
本发明涉及罐用钢板及其制造方法。罐用钢板以质量％计含有C：0.0030％以下，Si：0.02％以下，Mn：0.05％以上且0.60％以下，P：0.020％以下，S：0.020％以下，Al：0.010％以上且0.100％以下，N：0.0010％以上且0.0050％以下，Nb：0.001％以上且0.050％以下，其余部分由Fe和不可避免的杂质构成，((111)[1-21]晶向的衍射强度)/((111)[1-10]晶向的衍射强度)≥1.0，在轧制方向和水平面内与轧制方向成90°的方向上，拉伸强度TS≥550，断裂伸长率El>-0.02×TS+17.5。
摘要（英）：

The invention relates to a steel sheet for cans and a manufacturing method thereof. 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 balanceFe and impurities. Diffracted intensity of (111) [1-21] orientation and diffracted intensity of (111)[1-10] orientation are not less than 1.0; in a rolling direction and 90-degree direction from the rolling direction in a horizontal plane, tensile strength TS is not less than 550 MPa and fracture elongation E1 > -0.02*TS+17.5.
