A PROCESS FOR PRODUCING A NICKEL-CHROMIUMMOLYBDENUM BASE ALLOY

A nickel-chromium-molybdenum base alloy characterised by exceptional structural stability when exposed at temperatures upwards of 1800 DEG F (980 DEG C) for prolonged periods of time, such as 10 000 hours. and consisting of about 19 to 30% chromium, less than 0.25% silicon, 0.05 to 0.15% carbon, 7.5...

Zusammenfassung:	A nickel-chromium-molybdenum base alloy characterised by exceptional structural stability when exposed at temperatures upwards of 1800 DEG F (980 DEG C) for prolonged periods of time, such as 10 000 hours. and consisting of about 19 to 30% chromium, less than 0.25% silicon, 0.05 to 0.15% carbon, 7.5 to 9% molybdenum, about 7.5 to 20% cobalt, up to 0.6% titanium, about 0.8 to 1.5% aluminum, up to 0.006% boron, up to 0.1% zirconium, up to 5% iron, up to 5% tungsten and the balance being essentially nickel, said alloy being further characterized by an average grain size coarser than about ASTM 5.
