ABSTRACT:
A high-temperature sulfidation-corrosion resistant nickel-base alloy includes 12.about.15 weight % of cobalt, 18.about.21 weight % of chromium, 3.5.about.5 weight % of molybdenum, 0.02.about.0.1 weight % of carbon, at most 2.75 weight % of titanium, and at least 1.6 weight % of aluminum. The remainder is essentially of nickel except for impurities. The high-temperature sulfidation-corrosion resistant nickel-base alloy has sufficient high-temperature strength and is highly resistant to a high-temperature sulfidation corrosion.
