| Name | Material And Function | |||
| Material | Advantage | Material | Advantage | |
| Work Roll | C12Mo1V1 | Rolling silicon steel, stainless steel. rolling force ≤200KM，strip thickness ≤0.03mm,Rolling campaign 150tons. | HSS | HSS can reach max. Hardness 65HRC. Double rolling campaign of Cr12Mo1V1. So the distortion of the roll under huge pressure is small, and the deviation width of the plate can reach to a tiny tolerance. With the high hadness the change over time can be almost twice of C12Mo1V1 |
| 1st Intermediate Roll | Cr5NiMoH | Barrel hardness 58-60HRC, rolling campaign 1000tons. | Cr8NiMoH | Rolling campaign ≥1500tons，roughness drop ≤20%. |
| 2IMR | SHSS | The basic material of the material catalog. It applied in the prototype stage of the mill. The Barrel hardness 56--58HRC, rolling campaign 2000tons. Recommended roll material on new production line’s at the initial rolling stage. | Cr5NiMoH | Hardness 56--58HRC, better wear resistance ability than SHSS. Rolling campaign ≥3200tons. Put service in the normal rolling stage. |
| Summary |
According to different rolling purpose, recommend the following roll matching combination. Cr12Mo1V1+Cr5NiMoH+SHSSS Cr12Mo1V1+Cr8NiMoH+Cr5NiMoH |
