How do hardness and microstructure determine abrasive resistance?
A lot of my customers put hardness as a priority condition to value the abrasive resistant characteristics of wear plates.
Here I hope to declare some points as below,
- High hardness does not mean good wear resistance
- The material’s microstructure and not its hardness determines abrasive resistance wear characteristics
- Chemical composition & bulk hardness influence abrasion resistance
- Abrasion resistance is not apparent in a hardness test but in an actual wear test such as ASTM G65.
