Chromium Carbide/Cladded Wear Steel Plate/ Impact Resistance Plate/Wear and Impact Resistance
Chromium carbide cladded wear steel plate is manufactured by mild steel based, epositing chromium-rich, abrasion-resistant materials more than 20% chrome carbide . 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.
