Hard Alloy Ball G25 Bearing Balls

Product Name:

Hard Alloy Balls is a range of cobalt-chromium alloys designed for wear resistance, heat resistance andcorrosion resistance.

Hard Alloy Ball valve and valve seat standard valve ball Ball valve and valve seats is widely used in petroleum industry,

especially for oil well pump, such as sucker rod pump. in marine exploration, heat exchanger.

Hard Alloy balls Feature:

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.
