Abstract
Disclosed is a nickel-base alloy having a low coefficient of thermal expansion and a high degree of corrosion and oxidation resistance for use without a coating. The high strength alloy is not notch sensitive under impact and has very short term ordering to A.sub.2 B structure in aging. The alloy nominally contains, in weight percent, 8 chromium, 25 molybdenum, about 0.003 boron, about 1 iron, about 0.5 manganese, about 0.4 silicon and the balance nickel plus normal impurities.
