< Resistance To Friction >
At both room temperature and high temperature, Stellite alloy ball has good resistance to friction or holding-on. They can keep better degree of finish. Low friction coefficient between 0.11 and 0.15, It would depend on friction of the object's surface finish. Stellite alloy ball very suitable for as the valve sealing surface.
 
< High Temperature Resistance >
At normal temperature, Stellite alloy ball has medium hardness with the cemented carbide. But in the high temperature of 500 ~ 980 ºC, Stellite alloy ball has good hardness, excellent thermal fatigue resistance and preeminent hot corrosion resistance.
 
< Aero-corrosive Resistance >
Cavitation wear is a liquid containing solid particles and gas. When it flows rapidly in material surface, It would be a bubble, There was an ultrasonic wave in high breaking. This kind of phenomenon will cause fatigue damage in the material surface,have foveolate damage, And then Piece fall off. Environment of heat and corrosion,It will Accelerate the process of cavitation with solid particles in the liquid friction. Similar to the above situation with internal combustion engine valve, decompression valve, steam turbine, gas turbine and thruster.Stellite alloy can be quite a good withstand the harsh environment of the cavitation.
