Production process of our bushings
1. Powder metallurgy process
A. Better metallurgical structure, better strength
B. Various types of automatic pressing machines from 3 tons to 630
tons. The ordered profiles can be very flexible.
2. Investment casting process
Different volume of furnaces, the order quantity can be very
CNC, lathing, drilling, milling, grinding, wire cutting, polishing
Technical requirements of the stellite parts
Dimensions, drawings, tolerance, surface finish, radius, as your
Let us know your demands, we’ll feedback you within 2 hours.
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.
