Product Features
1. High-temperature resistance: the strength remains 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
It is dispersed in a CoCr alloy matrix and 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 other mediums.
