| Grade | Recommended applications |
| YGH20 | Maximum hardness,escellent wear resistance in the series .Used in the last 1-2 stands of good high speed rolling mills for rolling common and hard steel bars. |
| YGH25 | Higher wear resistance,moderate impact resistance in the series.Used in the last 1-3 stands of good high speed finishing rolling mills for rolling common and hard steel bars. |
| YGH30 | Moderate wear resistance and impact resistance .good for general purposes .Used in the last 1-4 stands or all stands of finishing mills. |
| YGH40 | Best for general purpises.Used in the front stands of good rolling mills and in the rear stands of common rolling mills. |
| YGH45 | Used in the first and second stands of finishing rolling mills and in the stands of pre-finishing rolling mills.For every stand of rolling lines for low speed rolling.Low precision and unstable operations. |
| YGH55 | Maximum binder content in YGHseries,good toughness and themal crack resistance.Used in the stands of pre-finishing rolling mills and for roll rings for hot rolling of ribbbed steel. |
