摘要

A steel plate for a cap for a bottle having sufficient strength and formability even when it is thinned, a method of manufacturing the same, and a cap. C: not more than 0.0050%, Si: not more than 0.10%, Mn: not less than 0.05% nor more than 0.50%, P: not more than 0.050%, S: not more than 0.050% : 0.0040% or less, B: 0.0005% or more and 0.0020% or less, the balance being Fe and unavoidable impurities, having a yield strength in the rolling direction of 500 MPa or more and an average Langmuir value (r) of 1.1 And an in-plane anisotropy (? R) of the Langford tooth is not less than -0.3 and not more than 0.3.
