Cobalt Alloy Valve Cage For Oil / Gas / Well Pump 38 - 44 HRC Hardness 0



Advantages of our valve seat and ball


1. High temperature resistance

The strength keeps stable up to 800℃ and it can even momentarily used at 1200℃.


2. Wear resistance

Due mainly to the unique inherent characteristics of the hard carbide phase dispersed in a

CoCr alloy matrix, it has exceptional wear and galling resistance.


3. Corrosion resistance

This exellent and lovely property allows this kind of material parts to be used in oil&gas, slurry, acid liquid and any other mediums.


4. Production process

Powder metallurgy pocess, it has better strength than casting parts, better granule structure andavoiding the troubles caused by casting defects.
