Abstract

PURPOSE:To avoid color shift and obtain good image quality by constituting the parts of the metal material which is incorporated in a glass tube using a dual phase steel sheet. CONSTITUTION:The metal material parts which are incorporated in a glass tube of a color cathode-ray tube, for example, a shadow mask 4, a magnetic shield 5, and an electron gun 6, as required, are constituted using a double dual phase steel sheet, especially a Dual Phase high reinforced thin steel sheet. When the blackening film of Fe3O4 is formed on each surface in the status of the metal material parts, yield stress can be improved by performing required heat treatment.
