Abstract
A steel sheet for preparing a heat shrink band effective for preventing the color drift is provided by a steel sheet having 24 kg/mm2 or higher of yield stress and 400 or higher of the product between the permeability μ under a magnetic field of 0.3 Oe and the sheet thickness.
Claims4
A steel sheet for preparing a heat shrink band effective for preventing a color drift, wherein said steel sheet contains 0.5 to 3.0% by weight of Si;
- has 24 kg/mm2 or higher of yield stress;
- and wherein the product μ×t=600 mm or higher where μ is the permeability under a magnetic field of 0.3 Oe and t is the sheet thickness.
A steel sheet for preparing a heat shrink band effective for preventing a color drift, wherein said steel sheet contains 0.005% by weight or less of C, 0.005% by weight or less of N, 0.1% by weight or less of P, 0.02% by weight or less of S, 0.5 to 3.0% by weight of Si, 1.0% by weight or less of Mn, and 1.0% by weight or less of sol. Al;
- has at least 24 kg/mm2 of yield stress;
- and wherein the product μ×t=600 mm or higher where μ is the permeability under a magnetic field of 0.3 Oe and t is the sheet thickness.
A steel sheet for preparing a heat shrink band effective for preventing a color drift, wherein said steel sheet contains 0.3 to 3.0% by weight of Si;
- has 24 kg/mm2 or higher of yield stress;
- and wherein the product of μ×t is higher than 780 mm where μ is the permeability under a magnetic field of 0.3 Oe and t is the sheet thickness.
