High nickel chromium alloy.

摘要

An oxidation resistant nickel-chromium based alloy possessing good stress rupture characteristics at elevated temperature and controlled grain size and containing, in weight percent, about 55-65% nickel, about 19 to 28% chromium, about 0.75 to 2% aluminium, about 0.2 to 1% titanium, about 0.04 to 0.1% nitrogen, up to about 0.1% carbon, up to about 1% each of silicon, molybdenum, manganese and niobium, up to about 0.1% boron, up to about 0.1% calcium, up to about 0.1% magnesium, the ratio between the silicon and titanium contents is preferably about 0.75 to 3.
