摘要：
A precipitation-hardening-type Ni-base alloy exhibiting improved resistance to stress corrosion cracking in a sour gas atmosphere containing elemental sulfur at high temperatures is disclosed. The alloy consists essentially of, by weight %;______________________________________ Cr: 12-25%, Mo: over 9.0 and up to 15%, Nb: 4.0-6.0%, Fe: 5.0-25%, Ni: 45-60%, C: 0.050% or less, Si: 0.50% or less, Mn: 1.0% or less, P: 0.025% or less, S: 0.0050% or less, N: 0.050% or less, Ti: 0.46-1.0%, Al: 0-2.0%. ______________________________________
