Stellite 20 Cobalt Based Alloy Valve Balls is made from is a hard alloy that can withstand various types of abrasion and
corrosion as well as high temperature oxidation.
The cobalt-base alloy was invented by American Elwood Hayness in 1907.
The Stellite alloy has major component of cobalt, containing a considerable amount of nickel, chromium, tungsten and
a small amount of molybdenum, niobium, tantalum, titanium, lanthanum, etc..Occasionally it contains an alloy of iron.
According to the composition of the alloy, they can be made into wire, powder for hard surface surfacing, thermal spraying,
spray welding, etc.. It also can be made into cast forging parts and powder metallurgy parts.
We produce Stellite 20 Cobalt Based Alloy Valve Balls with centrifugal cast process, investment process and resin sand cast process.
