Features and FAQ

Product Features

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 excellent and lovely property allows this kind of material parts

    to be used in oil and gas, slurry, acid liquid, and any other mediums.
