High Speed Steel Rolls
High Speed Steel Rolling Rolls usually short as HSS Rolls, the microstructure of HSS Rolls shows fine and diffuse carbide of MC and M6C embedded in the Martensite. The performance of wear resistance, thermal hardness and thermal fatigue resistance of HSS roll is excellent. So it is widely used for Finishing Work Rolls for Wire and Bar Mills.
