Chromium carbide overlay (CCO) is a wear-resistant steel plate created by welding a hard, chromium-rich carbide layer onto a mild steel base. This engineered surface dramatically increases hardness and abrasion resistance while maintaining structural flexibility. It is primarily used in mining, quarrying, cement, steel, and power-generation applications where severe wear and impact are common, such as chutes, buckets, hoppers, and liners.
