Three-Layer Coated Pins

We use chemical vapor deposition (CVD) to apply 3 layers of coating - TiC, TiCN and TiN - to the surface of the base material.

By using multilayer deposition to create multi-functionality, we have achieved a high degree of hardness, and our three-layer coated pins also have excellent seize resistance, abrasion resistance, and corrosion resistance.

Three-layer coated pins are indispensable when manufacturing steel cord for tires.
