摘要
Process for the mfr. of an iron-nickel alloy shadow mask comprises: (a) providing a metal sheet pierced with uniformly distributed hole, the metal sheet comprising an alloy comprising (in wt.%): 35.5-37 Ni; max. 0.5 Co; max. 0.1 Cr; max. 0.1 Cu; max. 0.1 Mo; max. 0.1 V; max. 0.1 Nb; max. 0.1 Mn; 0.03-0.15 Si; max. 0.001 S; 0.0001-0.002 Ca; 0.0001-0.002 Mg; max. 0.005 Al; max. 0.01 O; max. 0.002 C; max. 0.005 N; max. 0.003 P; 0.001 H; max. 0.001 B; balance Fe plus usual impurities, the following relationships satisfied: max. S = 0.02 x Mn + 0.8 x Ca + 0.6 x Mg Cr + Cu + Mo + V + Nb + Si = max. 0.15; (b) heat treating the sheet to obtain a grain size which defined by ASTM E112-88,12.4 is greater or equal to 7 ASTM; and (c) forming the sheet to the required shape. The shadow mask is also claimed.
