Abstract
A nickel-base alloy excellent in corrosion resistance at high temperatures, which consists essentially of, in weight percentage: PA1 Carbon -- 0.04 to 0.25%, PA1 Chromium -- 10.0 to 25.0%, At least one element selected from the group consisting of 0.1 to 30.0% iron, 0.1 to 25.0% tungsten, 0.1 to 10.0% molybdenum and 0.05 to 30.0% cobalt -- 50.0% at the maximum, PA1 Manganese -- 0.4 to 1.5%, PA1 Silicon -- 0.05 to 0.5%, preferably 0.05 to 0.2%, and PA1 Nickel and inevitable impurities -- balance; Said alloy having excellent corrosion resistance at high temperatures in an atmosphere of a low oxidizing potential. Said alloy contains, as required, the following additional elements: PA1 Boron -- 0.001 to 0.05%, PA1 Zirconium -- 0.1 to 0.1%, and At least one element selected from the group consisting of 0.001 to 0.02% magnesium, 0.001 to 0.05% calcium and 0.001 to 0.02% rare earth elements.
