| Hardness Scale | Minimum Acceptable Value | Maximum Acceptable Value |
|---|---|---|
| Rockwell C (HRC) | 20 | 68 |
| Vickers (HV) | 238 | 940 |
| Brinell (HB / HBW) | 226 | 705 |
Measures indentation hardness using a diamond cone indenter and a heavy load. Commonly used for hard materials like heat-treated steels.
Uses a square-based diamond pyramid indenter. Suitable for a very wide range of materials, from very soft to very hard.
Uses a hard steel or carbide ball pushed into the surface under a specific load. Provides a macro-hardness value representing a larger area.
