Description |
Belonging to hyper-eutectoid steel, have excellent cracking resistance and anti-cold fatigue crack, wear resistance and hardness drop small, which is the same as the Semi- steel roll. |

For extend the life of roller
Secondary service: provide mixed materials of antirust and anti-friction and heat-resisting
