Abstract
An alloy sheet containing Fe, Ni and Cr has an average austenite grain size of 15 to 45 .mu.m and a degree of mixed grain for austenite grain size of 4.5 to 50%; the alloy sheet has a gathering degree of the {331} plane on a surface of the alloy sheet of 8 to 35%, a gathering degree of the {210} plane of 1 to 20% and a gathering degree of the {211} plane of 2 to 20%; the degree of mixed grain is expressed by the equation: (.vertline.0.5 Dmax-D.vertline./D).times.100 (%), where D is an average austenite grain size, and Dmax is a maximum austenite grain size in said alloy sheet.
