Smooth CCO Plate
Smooth CCO plate was manufactured using advanced fusion bond submerged arc welding technology to apply a highly abrasive resistant chromium carbide on to a steel substrate producing consistent chemistry and micro structure (austenitic) with smooth overlay deposit.
This product is usually referred to as chromium carbide overlay (CCO) plate on the market. The hardfacing overlay is suitable for severe abrasive wear and impact applications.
The ultimate hardfaced product for your application depends on the material–whether rock, sand, gravel or other substance–striking or sliding along the surface of your wear part. It also depends on the angle and speed of impact as well as the operating temperature.
