Hartmetall-Überzugsplatte: Wear Resistance Comparison with Wear Steel and High Manganese Steel
Carbide overlay plate is a composite wear-resistant steel plate produced by depositing a high-hardness carbide-rich layer (mainly chromium carbide or complex carbides) onto a carbon steel or low-alloy steel base. It is widely used in severe abrasion environments such as mining, Zement, Stromerzeugung, und Schüttguthandling.
To understand its performance advantage, it is commonly compared with traditional wear-resistant steel plates (such as NM400/NM500) and high manganese steel (Mn13). These three materials represent different wear protection mechanisms and hardness levels.
1. Härtevergleich
| Material | Härtegrad | Surface Characteristics |
|---|---|---|
| Carbide overlay plate | HRC 58–65 (bis zu 70+ with tungsten carbide) | Extremely hard carbide surface layer |
| Verschleißfester Stahl (NM400/NM500) | HB 400–500 | Uniform hardened steel structure |
| Stahl mit hohem Mangangehalt (Mn13) | HB 180–220 (before work hardening) | Soft initially, work hardens under impact |
Carbide overlay plates have the highest initial surface hardness among the three materials.
2. Wear Resistance Mechanism Difference
| Material | Verschleißmechanismus |
|---|---|
| Carbide overlay plate | Hard carbide particles resist abrasion directly |
| Stahl tragen (NM/AR) | Bulk hardness resists impact and wear |
| Stahl mit hohem Mangangehalt | Surface becomes harder under repeated impact (Kaltverfestigung) |
Each material is optimized for different wear conditions rather than competing directly.
3. Performance in Different Working Conditions
| Zustand | Best Material |
|---|---|
| High sliding abrasion (Kohle, Zement, Erz) | Carbide overlay plate |
| Gemischte Wirkung + Abrieb | Verschleißfester Stahl (NM400/NM500) |
| Starke Wirkung (Brecher, Hämmern) | Stahl mit hohem Mangangehalt |
4. Key Difference in Hardness Behavior
- Carbide overlay plate: High hardness from the start (stabile Verschleißfestigkeit)
- Stahl tragen: Ausgewogene Härte und Zähigkeit
- Stahl mit hohem Mangangehalt: Low initial hardness but increases under impact
5. Lebensdauervergleich
- Carbide overlay plate: Longest life in abrasive sliding conditions
- Stahl tragen: Stable life in mixed wear conditions
- Stahl mit hohem Mangangehalt: Best in repeated impact environments
Service life depends heavily on correct material selection for the working condition.
6. Why Carbide Overlay Plate Performs Better in Abrasion
- Extremely hard chromium carbide particles (HRC 58–65)
- Dense wear-resistant surface structure
- Low material loss under particle erosion
