Abstract
A nickel-chromium alloy excellent in a stress corrosion cracking resistance which is obtained by carrying out an annealing treatment under specific conditions, said alloy having the following composition: ______________________________________ in terms of % by weight, ______________________________________ 0.04% or less of C; 1.0% or less of Si; 1.0% or less of Mn; 0.030% or less of P; 0.02% or less of S; 40 to 70% of Ni; 25 to 35% of Cr; 0.1 to 0.5% of Al; 0.05 to 1.0% of Ti; 0.5 to 5.0% in all of one or more of Mo, W and V, and ______________________________________ the residue comprising substantially Fe. A nickel-chromium alloy further including 0.2 to 5.0% of Nb subject to Ti=0.2 to 1.0% and Nb/C=10 to 125.
