Patent number: 6423160Abstract: A stainless steel plate for a shadow mask, comprising 9 to 20 weight % of chromium (Cr), 0.15 weight % or less of carbon (C), 0 to 1.0 weight % of manganese (Mn), 0 to 0.2 weight % of titanium (Ti), 0 to 1.0 weight % of silica (Si), and 0 to 1.0 weight % of aluminum (Al); wherein the rest includes ferrite (Fe) and inevitable impurities, and in the inevitable impurities, the content of phosphor (P) is 0.05 weight % or less and the content of sulfur (S) is 0.03 weight % or less. Furthermore, the metal plate for a shadow mask after cold rolling or shape correction is performed is subjected to annealing treatment at the end-point temperature of the plate of 550 to 650° C. This steel plate has a coefficient of thermal expansion smaller than that of low carbon steel and is less expansive than invar alloy. Further, the steel plate has high strength that is acceptable for the shadow mask that is used under conditions where plastic deformation is small at high temperature and high tension is applied.Type: GrantFiled: January 4, 2001Date of Patent: July 23, 2002Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Nozomu Arimoto, Hayato Kita, Masahiro Aoki, Shinji Tsuge, Kazuhiko Adachi
