Abstract

OBJECT] 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 AND 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. [MEANS OF SOLUTION] THE METHOD COMPRISES THE STEPS OF COLD-ROLLING A LOW CARBON STEEL SHEET CONTAINING 0.05 TO 2.5 WT% OF CU, OR 0.5 TO 2.5 WT% OF CU AND 0.00.1 TO 0.4 WT% OF P, AND SUBJECTING SAME TO AGEING AT A TEMPERATURE OF 300 TO 700O C. ALTERNATIVELY, THE METHOD COMPRISES THE STEPS OF: COLD-ROLLING THE LOW CARBON STEEL SHEET SAME AS MENTIONED ABOVE, AND SUBJECTING SAME TO PROCESS ANNEALING AT A TEMPERATURE OF 500 TO 800O C, THEN ANOTHER COLD-ROLLING, AND AGEING THEREAFTER.
