Product Description
High speed steel mill rolls usually short as HSS Rolls, the microstructure of HSS Rolls shows fine and diffuse carbide of MC and M6C embedded in the martensite. Finishing stand rolls of wire and bar mill should have a good wear resistance performance and resistance to crack pieces off. Effectively guarantee the rolled surface finish and negative tolerances of rolling. These types of roll ensure that the plats surface quality and dimensional accuracy with a high wear-resistant properties and anti-crack, anti-peeling, anti-prints capacity, So it is widely used on finishing stand of wire and bar mill.
