TABLE 1 Properties of high hardness high impact metal abrasive for reducing stress corrosion of steel
| Numbering | Rockwell hardness/HRC | Corrosion rate/mg/(dm. D) |
| Example 1 | 60.91±0.32 | 0.10±0.11 |
| Example 2 | 66.33±0.45 | 0.09±0.32 |
| Example 3 | 71.64±0.16 | 0.08±0.63 |
| Example 4 | 80.12±0.28 | 0.05±0.45 |

| Comparative example 2 | 52.89±0.73 | 0.25±0.91 |
| Comparative example 3 | 35.57±0.22 | 0.51±0.56 |
As shown in fig. 1 and table 1, the rockwell hardness of the metal abrasive in the examples of the present invention is significantly higher than that of the comparative example, and the corrosion rate is significantly lower than that of the comparative example, which shows that the metal abrasive of the present invention has excellent properties such as high hardness, good impact resistance and wear resistance, and a slow corrosion rate, and can be mass-produced.
By adopting the preparation method of the metal abrasive, the hardness is within the range of 35.57-80.12HRC, the corrosion speed is within the range of 0.05-0.51 mg/(dm d), wherein the hardness and the corrosion speed of the embodiment 4 are optimal, the hardness reaches 80.12HRC, and the corrosion speed reaches 0.05 mg/(dm d), so that the performance is influenced by adding too much or too little metal scandium within a certain amount; the performances of the comparative examples 1, 2 and 3 are poor and have no obvious difference, so that the impact resistance and the wear resistance of the metal abrasive are obviously improved and the corrosion speed is obviously reduced under the condition of realizing high hardness by considering the influence of the comprehensive performance of the metal abrasive.
