Grade YGH
| Grade | Recommendation applications |
| YGH20 |
With high hardness, i t is used for rolling of common wire and hard wire at the last two stands of finishing mill |
| YGH25 |
With good wear-resistance and moderate impact-resistance, it is used at the last two stands of finishing mill |
| YGH30 |
With moderate wear-resistance and impact-resistance and good versatility, t is used at the last four resistance or all the stands |
| YGH40 |
With best versatility, it is used at the front stands of finishing mill and rear stands of common rolling mill |
| YGH45 |
It is used at the first two stands of finishing mill as well as the stands of pre-finishing mill, and also applied of the stands of rolling machine with low speed and accuracy a nd varied technology |
| YGH55 |
Because of fine toughness and hot crack resistance,i t is used for the stands of pre-finishing mill and hot rolled steel collar |
