Cobalt superalloy
Patent
·
OSTI ID:5309240
Disclosed is a cobalt-base superalloy containing about 32% cobalt, 8% nickel, 26.5% chromium, 2.5% tungsten, 5% niobium, about 1% each manganese and silicon, about 0.4% carbon, and the balance about 23% iron plus incidental impurities and modifiers normally found in alloys of this class. The alloy is readily processed in the form of wrought products, castings, metal powder and all forms of welding and hardfacing materials. The outstanding characteristics of the new alloy include the resistance to cavitation erosion and galling, low cost and minimal use of strategic metals.
