Abstract

The object of the present invention is to provide a material for an aperture grille for use in a color picture tube, which has an excellent yield strength, high temperature creep strength and superior magnetic characteristics to currently used materials. The other objects are to provide a producing method of the above mentioned material for an aperture grille and to provide an aperture grille made thereof and a color picture tube incorporating the aperture grille. The method comprises the steps of cold-rolling a low carbon steel sheet containing 9 to 30 wt percent of Ni or 9 o 30 wt percent of Ni and 0.1 to 5 wt percent of Co; and annealing the cold-rolled steel sheet at a temperature of 400 to 500 degree C. Alternatively, the method comprises the steps of: cold-rolling the low carbon steel sheet same as mentioned above; subjecting the cold-rolled steel sheet to process-annealing at a temperature of 500 to 800 degree C and another cold-rolling; and thereafter annealing same.
