| Grade | Recommended applications |
| YGH20 | Maximum hardness ,excellent wear resistance in the series.Used in the last 1-2 stands of good high speed line mills for rolling common and hard bars. |
| YGH25 | Higher wear resistance,moderate impact resistance in the series.Used in the last 1-3 stands of good high speed line mills for rolling common and hard bars. |
| YGH30 | Moderate wear resistance and impact resistance,good for general purposes.Used in the last 1-4 stands of finish rolling mills. |
| YGH40 | Best for general purposes.Used in the front stands of good mills and in the rear stands of common mills. |
| YGH45 | Used in the first and second stands of finish rolling mills and in the stands of prefinish rolling mills.For every stand of the rolling lines for low speed rolling,low precision and unstable operation. |
| YGH55 | Maxmum binder content in YGH series,good toughness and crack resistance.Used in the stands of perfinish rolling mills and for rolling screw thead steel |
