Abstract

PURPOSE: To produce an Ni-base alloy member excellent in SCC resistance by subjecting an Ni-base alloy having a specific composition consisting of Cr, Mo, Nb, Ta, Fe, and Ni to specific solid solution heat treatment, to cooling, and then to plastic working at specific draft.
CONSTITUTION: An Ni-base alloy having a composition consisting of, by weight, 18-25% Cr, 5-12% Mo, 2-6% Nb and/or Ta, ≤10% Fe, and the balance Ni with inevitable impurities is subjected to solid solution heat treatment at 950-1150°C, followed by temporary cooling. It is preferable to perform the above cooling by means of rapid cooling to prevent the formation of Cr carbide. After cooling, the above alloy is subjected to plastic working at a draft of ≥10%, preferably of 10 to about 30%. By this method, the Ni-base alloy member improved in SCC resistance as well as in mechanical properties can be obtained.
