    摘要: A shadow mask is composed of an iron-based alloy plate containing 31.0-38.0 weight % of nickel and 1.0-6.5 weight % of cobalt. The iron-based alloy has a crystal grain size number of 10 or more and 12 or less, has a crystal grain size of 50 &mgr;m or less in a cross section in a direction parallel and normal to a rolling direction of the iron-based alloy plate, and has an average crystal grain size of 30 &mgr;m or less in a cross section in a direction parallel to the rolling direction of the iron-based alloy plate.

    摘要: A shadow mask for a Braun tube is composed of an iron-based alloy plate of a low thermal expansion structure containing nickel and cobalt, and the iron-based alloy plate has a crystal grain size of more than 6.0 and less than 9.0 measured by a grain size measuring method prescribed in JIS (Japanese Industrial Standard) G0551, and 0.2% proof stress of more than 240N/mm2 and less than 320N/mm2.
