Title
(EN) COLOR PICTURE TUBE SHADOW MASK MATERIAL
(FR) MATERIAU POUR MASQUE PERFORE DE TUBE D'IMAGES COULEUR
Abstract
(EN)
A color picture tube shadow mask material excellent in tensile strength and high-temperature creep strength, a shadow mask and a picture tube incorporating the mask, wherein the shadow mask material uses a low-carbon alloy steel plate containing 0.05 to 2.5 wt.% of Cu and 0.001 to 0.4 wt.% of P, or 0.05 to 2.5 wt.% of Cu, 0.001 to 0.4 wt.% of P and 0.01 to 1.75 wt.% of Ni.
(FR)
L'invention concerne un matériau pour masque perforé de tube d'images couleur, présentant une excellente résistance à la traction et au fluage, un masque perforé, et un tube d'images couleur comprenant ledit masque. Le matériau pour masque perforé est constitué d'un alliage d'acier à faible teneur carbone contenant 0,05 à 2,5 % en poids de Cu et 0,001 à 0,4 % en poids de P, ou 0,05 à 0,25 % en poids de Cu, 0,001 à 0,4 % en poids de P, et 0,01 à 1,75 % en poids de Ni.
