摘要：
It is an object of this invention to provide a shadow mask material for use in a color picture tube excellent in tensile strength and excellent in high temperature creep strength, a shadow mask and a picture tube incorporating the same. For this purpose, the shadow mask material according to this invention uses a low carbon alloy steel sheet containing from 0.05 to 2.5% by weight of Cu and 0.001 to 0.4% by weight of P, or from 0.05 to 2.5% by weight of Cu, from 0.001 to 0.4% by weight of P and from 0.01 to 1.75% by weight of Ni.
