Chemical compositions and properties (%)
Advantages of our valve seat
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
and avoiding the troubles caused by casting defects.
