Influence of chemical composition on rupture test properties at 1500 F of forged chromium-cobalt-nickel-iron base alloys

J. W. Freeman, J. F. Ewing, A. E. White

The influence of systematic variations of chemical composition on rupture properties at 1500 degrees F was determined for 62 modifications of a basic alloy containing 0.15 percent carbon, 1.7 percent manganese, 0.5 percent silicon, 20 percent chromium, 20 percent nickel, 20 percent cobalt, 3 percent molybdenum, 2 percent tungsten, 1 percent columbium, 0.12 percent nitrogen, and the balance iron.
