Die herausragenden Merkmale der YGH-T Roll Ring, die sich von konventionellen Zementkarbid Roll Ringe in der Praxis sind wie folgt:
| Grade | Chemical composition | Mechanical properties | Physical properties | |||||
|---|---|---|---|---|---|---|---|---|
| Co+Ni % | WC % | Hardness HAR | T.R.S MPa | Density g/cm3 | Sandvik | Cerametal | Sintermet | |
| YGH10T | 6 | 90 | 88 | 2250 | 14.90 | H6T | CE65 | SM80 | 
| YGH20T | 12 | 88 | 86 | 2750 | 14.30 | ? | ? | SM64 | 
| YGH30T | 15 | 85 | 85 | 2800 | 14.00 | H15C | CE79 | SM59 | 
| YGH40T | 18 | 82 | 83 | 2700 | 13.70 | ? | CE103 | SM65 | 
| YGH50T | 22 | 78 | 82 | 2700 | 13.40 | H25P | CE112 | SM61 | 
| YGH60T | 30 | 70 | 79 | 2500 | 12.70 | C30P | CE260 | SM62 | 
| Grade | Recommended applications | 
|---|---|
| YGH10T | Maximum hardness, excellent wears resistance in the series. Used in the last 1-2 stands of good high speed finishing mills for rolling common and hard steel bars. | 
| YGH20T | Higher wear resistance, moderate impact resistance in the series. Used in the last 1-3 stands of good high speed finishing mills for rolling common and hard steel bars. | 
| YGH30T | Moderate wear resistance and impact resistance, good for general purposes. Used in the last 1-4 stands or all stands of finishing mills. | 
| YGH40T | Best for general purposes, used in the front stands of good mills and in the rear stands of common mills. | 
| YGH50T | Used in the first and second stands of finishing mills and in the stands of pre-finishing rolling mills. For every stand of rolling lines for low speed rolling, low precision and unstable operation. | 
| YGH60T | Maximum binder content in YGH series, good toughness and thermal crack resistance. Used in the stands of pre-finishing rolling mills and for roll rings for hot rolling of ribbed steel. |
