9. What`s the Feasures of our valve seats ?
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.
