Zusammenfassung:PROBLEM TO BE SOLVED: To reduce segregation occurring in a steel ingot, to make it possible to product a large-size member so far considered to be impossible, and to secure mechanical properties equal to those of Inconel (R) 706 alloy by providing a composition consisting of Ni, Cr, Al, Ti, Nb, and the balance iron with inevitable impurities and preferably containing B and further Mo and/or W. SOLUTION: This alloy has a composition consisting of, by weight ratio, 35-45% Ni, 15-25% Cr,
