High chromium wear-resistant steel plates are a type of high-performance abrasion-resistant material made by alloying steel with a high chromium content, typically above 12–20%, which promotes the formation of a large volume of hard chromium carbide phases within the microstructure. These carbides significantly enhance surface hardness, wear resistance, and impact resistance, making the plates highly effective in environments with severe abrasive wear such as mining, cement, metallurgy, power generation, and bulk material handling. Compared with conventional steel, High chromium wear-resistant steel plates offer a much longer service life, reduced maintenance frequency, and improved operational efficiency, making them a preferred choice for industrial wear protection applications.
Core Advantages
1. Top-tier wear resistance: The wear-resistant layer hardness can reach HRC58-65, with resistance to abrasive and erosive wear 2-3 times that of NM wear-resistant steel and more than ten times that of ordinary carbon steel.
2. Stable high-temperature performance: It does not soften at high temperatures of 500-600℃, maintaining stable hardness, making it suitable for high-temperature working conditions.
3. Corrosion Resistance: High chromium content forms a passivation film, resisting corrosion from weak acids, alkalis, and dust.
4. Hardness Activation Required: Maintains high hardness under normal conditions, suitable for static, low-impact wear scenarios.
5. Strong Adaptability of Composite Plates: The bimetallic composite structure uses low-carbon steel as the substrate, improving upon the brittleness of high-chromium steel plates while balancing toughness and wear resistance.

|
Dominant Wear Resistance Type |
Excellent resistance to abrasive wear and sliding erosion wear |
Outstanding resistance to strong impact, extrusion, and wear |
|
Impact Resistance |
Integral high-chromium plates are brittle, composite plates have moderate impact resistance |
Excellent impact resistance, not easily broken under strong impact |
|
High Temperature Resistance |
Stable hardness at 500-600℃ |
Can withstand high temperatures up to 600℃, but high-temperature toughness will decrease |
|
Corrosion Resistance |
Excellent, chromium forms a passivation protective film |
Moderate corrosion resistance |
|
