摘要： A nickel-chromium alloy exhibiting enhanced stress rupture strength and grain size stability at elevated temperatures up to about 1260.degree. (2300.degree. F.) due to the affirmative formation of M.sub.6 C carbide within the alloy. The alloy is especially useful for turbine and engine applications.

摘要： A carburization-resistant alloy comprising in weight percent about 50 to about 55% nickel, about 16 to 22% chromium, about 3 to about 4.5% aluminum, up to about 5% cobalt, up to about 5% molybdenum, up to about 2% tungsten, about 0.03 to about 0.3% carbon, up to about 0.2% rare earth element, balance essentially iron. The alloy is useful for structures, objects, parts etc. which are exposed in use to carburizing atmospheres and which, periodically are subjected to oxidizing atmospheres. For example the alloys are useful for pyrolysis tubes used in the petrochemical industry which must periodically be subjected to oxidizing atmospheres to burn-out carbon deposits and which, during pyrolysis are in contact with atmospheres having log Po.sub.2 spanning at least the range of -17 to -26 and which exist at various temperatures.
摘要翻译：一种耐渗碳合金，其重量百分比为约50至约55％的镍，约16至22％的铬，约3至约4.5％的铝，至多约5％的钴，至多约5％的钼，至多约2 ％钨，约0.03至约0.3％的碳，至多约0.2％的稀土元素，余量基本上为铁。该合金可用于暴露在渗碳气氛中并周期性地经受氧化气氛的结构，物体，部件等。例如，该合金可用于石油化学工业中使用的热解管，其必须周期性地经受氧化气氛以燃烧碳沉积，并且在热解期间与具有至少-17至 -26，其存在于各种温度下。
