Abstract
THE OBJECT OF THIS 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 COMPARED TO CURRENTLY USED MATERIALS. THE OBJECT IS ALSO TO PROVIDE A PRODUCING METHOD OF THE ABOVE MENTIONED MATERIAL FOR AN APERTURE GRILLE, 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 9~30 WT% OF NI, OR 9~30 WT% OF NI AND 0.1~5 WT% OF CO; AND ANNEALING THE COLD-ROLLED STEEL SHEET AT A TEMPERATURE OF 400~500 °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 500~800 °C AND ANOTHER COLD-ROLLING; AND THEREAFTER ANNEALING SAME.
