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.
