Abstract (en)
An alloy sheet for making a shadow mask consists essentially of 34 to 38wt.% Ni, 0.07wt.% or less Si, 0.001wt.% or less B, 0.003wt.% or less O, 0.002wt.% or less N, and the balance being Fe and inevitable impurities. The alloy sheet has an average austenite grain size (Dav) of 10.5 to 15.0 mu m, a ratio of a maximum size to the minimum size of austenite grains (Dmax/Dmin) of 1 to 15, a Vickers hardness (Hv) of 165 to 220 and satisfying a relation of 10 x Dav + 80 >/= Hv >/= 10 x Dav + 50; and gathering degree of crystal planes on said alloy sheet surface of 14% or less for {111} plane, 5 to 75% for {100} plane, 5 to 40% for {110} plane, 20% or less for {311} plane, 20% or less for {331} plane, 20% or less for {210} plane, and 20% or less for {211} plane. <IMAGE>
