<p>A steel sheet for a heat shrink band which has a chemical composition in mass %: C:0.005 % or less, Si: 0.5 to 4 % , Mn: 2 % or less, P: 0.2 % or less, S: 0.04 % or less, sol.Al: 0.2 % or less, N: 0.01 % or less, B: 0.0003 to 0.004 %, O: 0.005 % or less, Sb: 0.002 to 0.1 % and balance: substantially Fe; and a steel sheet for a heat shrink band which further satisfies that a ratio of a B content to a N content, B/N, is 0.2 to 1. The steel sheet allows the production of a heat shrink band having high strength and also satisfactory magnetic shielding property.</p> |
