Pilot Pins
High performance cemented carbides for molding;Standard
Specification For Square Material and Standard Specifications Of
The Rings. Also we can produce the your drawing of ring.
- 100% raw material;
- Hip sintered, high hardness, high wear resistance;
- Tunable residual stress
- Electrochemical corrosion resistance
Polarization curve (corrosion current reduced, corrosion rate
decreased significantly, corrosion resistance improved
significantly)
