To obtain an alloy capable of meeting the recent demands for severer drawability and for improvement of stamping speed and most suitably used as an alloy stock for electron gun electrode.

The Fe-Cr-Ni alloy stock has a basic composition consisting of 15-20% Cr, 9-15% Ni and the balance essentially Fe and also has ≤0.03% cleanliness defined by JIS 0555. Moreover, when the aggregation degree of the (111) plane in the central part of stock sheet thickness after final annealing is represented by equation 1, αC(111)≤50% is satisfied. Further, when the similarly computed aggregation degree of the (111) plane in the surface layer part is represented by αS(111), αS(111)≤αC(111) is satisified.
