Abstract (en)

[origin: EP1445341A1] There is provided a Fe-Ni based alloy for shadow mask having high corrosion resistance, high rigidity and low thermal expansion and hardly generating rust even if being exposed in air in the course of circulation and transportation after the bright annealing as a middle step of the starting material production and a shadow mask material. A Fe-Ni based alloy for a shadow mask having an excellent corrosion resistance comprises C≤0.01 wt%, Si: 0.01-0.1 wt%, Mn: 0.01-0.1 wt%, Ni: 35-37 wt%, Cr≤0.1 wt%, Nb: 0.01-1.0 wt%, S≤0.0020 wt%, Al≤0.005 wt% and the balance being Fe and inevitable impurity, and a shadow mask material is comprised of the alloy having a proof strength at 0.2% of not less than 300 N/mm<2> and a thermal expansion coefficient of not more than 1.0x10<-6>/ DEG C.
