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.
