Historical origin:
Stellite alloy is a hard alloy that can resist various types of wear and corrosion as well as high temperature oxidation. Commonly known as cobalt-based alloy, Stellite alloy was invented by American Elwood Hayness in 1907.Stellite alloy is mainly composed of cobalt, containing a considerable amount of nickel, chromium, tungsten and a small amount of molybdenum, niobium, tantalum, titanium, lanthanum and occasionally a class of alloys containing iron.Depending on the composition of the alloy, they can be made into wire, powder used for hard surfacing, thermal spraying, spray welding and other processes, as well as cast and forged parts and powder metallurgy parts
Stellite Alloy applications:
Stellite 1£¬UNS R30001 Alloy is mainly composed of cobalt, containing a considerable amount of nickel, chromium, tungsten, a small amount of molybdenum, niobium, tantalum, titanium, lanthanum and occasionally a class of alloys containing iron.Depending on the composition of the alloy, they can be made into wire, powder (used in hardfacing surfacing, thermal spraying, spray welding and other processes), cast or forged parts and powder metallurgy parts.
Typical grades of Stellite alloy are:
Stellite1(UNS R30001),Stellite4,Stellite6(UNS R3006),Stellite12(UNS R30012),Stellite20,Stellite21(UNS R30021),Stellite31,Stellite100 etc.
