Grain size: Medium 1.2-1.6, fine grain 0.6-0.8μm is also available
The smaller the grain size, the higher the hardness, but the lower the impact resistance. If you have any questions about the carbide grades, feel free to contact us for more details.
OED can produce various types of carbide wear parts, including valve fittings, various stem seats with internal threads, external threads, etc. A variety of finely polished parts can be machined.
Carbide grades with cobalt or nickel are available.

Our advantages:
- CIP forming.
CIP Forming can eliminate the internal defects of raw sintered carbide blanks in particular. It can provide uniform density suppression products for the thick carbide strips/plate and special shape carbide products.
- Cryogenic process
The internal stress can be removed through the cryogenic process to improve the microstructure.
- Vibration process
The internal stress can be removed through the vibration process to improve the overall performance.
- Heat treatment
The service can be improved through the heat treatment process.
