Description
Chromium Carbide Overlay (CCO) Plates
CCO, or chromium carbide overlay, only contains chromium-rich carbides. Overlays can also be of the complex carbide type. In these products other alloys such as Nb, Mo, V and W are added to the chromium carbide.
Complex carbides are usually a preferred choice in hot wear situations since they can maintain full wear resistance in temperatures up to 600 °C (1100 °F). As complex carbides typically give 3-5 times longer service life compared to CCO, they are also suitable if the thickness of the overlay is restricted.
The overlay surface of CCO plate will consist of a series of beads with numerous hairline cracks in them. These properly spaced crosscheck cracks are a natural phenomenon and are beneficial to the material. The cracks propagate through the overlay and end at the fusion line.
Design Features
Cost effective solution when compared to traditional abrasion-resistant steels
Recommended for resistance to wear by abrasion, fretting, cavitation, and particle erosion in high temperature applications (up to 1100°F).
Ideal for mild to moderate impact abrasion resistance.
Low maintenance cost and easy installation.
