摘要： A method of making a steel sheet for a tension mask, including the steps of: hot rolling a steel consisting essentially of, by weight %, C: less than 0.1%, Si: 0.05% or less, Mn: 0.4 to 2%, P: 0.03% or less, S: 0.03% or less, sol.Al: 0.01% or less, N: 0.010% or more, and the balance of Fe; and annealing the cold rolled steel sheet, followed by a secondary cold rolling at a reduction rate of 35% or higher. The steel sheet produced by this method shows excellent creep resistance during blackening treatment and excellent magnetic shielding property with an anhysteretic permeability of 3400 or more at a DC bias magnetic field of 0.35 Oe, and therefore causes no color-deviation when applied to the tension mask.

摘要： A steel sheet for heat shrink band of the present invention has anhysteretic magnetic permeability of 15,000 or higher at 0.35 Oe and yield stress of 24 kgf/mm2 or more. The steel sheet can be manufactured by a method comprising the steps of: hot rolling and/or cold rolling a steel containing 0.01 to 0.15% C by weight; annealing the rolled steel sheet at a temperature ranging from 650 to 900° C.; and temper rolling the annealed steel sheet at a rolling reduction rate of 1.5% or less. A CRT made of the steel sheet causes very little color deviation and practically no deformation of the panel surface.
