    Abstract

    Chromium-nickel alloys containing 35 to 70 per cent chromium with additions of iron, molybdenum, and columbium have been precision cast and tested in stress-rupture at 1600 to 1800 F. Results surpassing many commercial alloys have been obtained, especially with alloys containing 40 to 45 per cent chromium, 2 to 10 per cent iron, 2 per cent molybdenum, and 2 per cent columbium. Higher chromium alloys exhibit high hardenability which may make possible high-temperature bearing applications. Forging of the 40 to 50 per cent chromium alloys is difficult, but possible, and should improve through vacuum melting.
