| 注： | |||||||
| 1、布氏硬度：主要用来测定铸件、锻件、有色金属、热轧坯料及退火件的硬度，测定范围 | |||||||
| ≥450。 | |||||||
| 2、洛氏硬度：HRA主要用于高硬度试件，测定硬度高于HRC67以上的材料和表面硬度，如 | |||||||
| 硬质合金、氮化钢等，测定范围HRA>70。HRC主要用于钢制件（如碳钢、工具钢、合金 | |||||||
| 钢等）淬火或回火后的硬度测定，测定范围HRC20-67。 | |||||||
| 3、维氏硬度：用来测定薄件和钢板制件的硬度，也可用来测定渗碳、氰化、等表面制件的 | |||||||
| 硬度。 | |||||||
