Beschreibung
Zusammenfassung:	PURPOSE:To improve the blackening treatability of a thin sheet for a shadow mask and to reduce the blackening treatment time by regulating the upper limit of specified elements contained in an Fe-Ni-(Co) alloy and limiting the accumulating degree of the crystal plane on the surface of the steel immediately before blackening treatment to a certain one or below. CONSTITUTION:In the Fe-Ni (Co) series alloy thin sheet for a shadow mask having a low thermal expansion coefficient, the content of H is regulated to
