Abstract
A steel sheet for a shadow mask consists essentially of not less than 0.015 wt percent of Cu and the balance being of Fe. At the same time, the said steel sheet is made of aluminum killed steel containing a more amount of Cu than that of S by not less than 0.02 wt percent so as to further improve etchability. The said steel sheet is obtained by being subjected to hot rolling. descaling. annealing. Primary cold-rolling, decarburization-annealing and finished cold-rolling, accordingly. A shadow mask made of the said steel sheet has an excellent etchability. A color picture tube incorporating this shadow mask can attain a clear, high quality picture.
