Precipitation hardening of cobalt alloys. B6B. Applications: heat-resistant material production: springs. Components subjected to mechanical stress at elevated temps. also requiring corrosion resistance. Vibration components requiring good elastic properties and adequate fatigue strength under reversals and parts required not to be ferromagnetic. Cobalt-nickel-chromium-iron alloy for use up to at least 600 degrees C: composition by wt.: Co 38-45%, Ni 22-28%, Cr 10-14%, Fe 5-10%, Mo 3-5%, W 3-5%, Ti 1.6-4%, Al 0.4-2%, Mn 0.3-1.5%, Si 0.2-1.5%, C less than 0.1%. Total 100%. |
