In practical applications within power plants, chromium carbide overlay plate offer significant advantages over other materials, primarily in the following aspects:

1. High Wear Resistance

Advantage: chromium carbide overlay plates are typically composed of a high-hardness wear-resistant layer (chromium carbide) and a tough base material ( low-carbon steel), effectively resisting wear from materials such as coal, slag, and dust.

Comparison: Ordinary steel or standard alloy steel wears out more quickly under the same conditions, requiring frequent replacement.

2. Impact Resistance

Advantage: The tough base material of chromium carbide overlay plates can absorb impact energy, preventing the material from cracking or peeling when struck by large particles.

Comparison: Ceramic or pure hard alloy materials, while highly hard, are brittle and prone to breaking under impact.

3. Corrosion Resistance

Advantage: The wear-resistant layer of chromium carbide overlay plates generally exhibits good corrosion resistance, capable of withstanding corrosion from flue gas, alkaline media, and wet desulfurization environments.

Comparison: Ordinary steel is prone to rust and corrosion in corrosive environments, resulting in a shorter service life.

4. Extended Equipment Lifespan

Advantage: The service life of chromium carbide overlay plates is several times or even more than ten times that of ordinary steel, significantly extending the operational life of equipment.

Comparison: Ordinary steel or non-wear-resistant materials require frequent replacement, increasing maintenance costs and downtime.
