D6 is not covered by Table 10
Table 10 covers the grades ASM lists as in common use. D6 (1.2436, SKD2) is not on that list, although the grade is still produced and supplied for long run blanking, cold forming punches and other high wear press work, so it is rated below from a second source.
| AISI steel number | Non-deforming properties | Safety in hardening | 강인함 | Resistance to softening | 내마모성 | 가공성 |
|---|---|---|---|---|---|---|
| 디6 | 좋은 | 좋은 | 가난한 | 공정한 | 최상의 | 가난한 |

The rating words are the book’s own four step scale of poor, fair, good and best, so they are not comparable one to one with the eight step scale used above. The book rates D6 with the same values as D3, which matches the chemistry, a D3 type steel with tungsten and vanadium added. Properties and the hardening and tempering schedule are on the D6 heat treatment page.
