High quality tungsten carbide roll rings for rolling mill are widely used as seal faces with resistant-wearing, high fracturing strength, high thermal conductivity, small thermal expansion coefficient. It is the best material to resist heat and fracture in all hard face materials.

Property:

1.High hardness & good wear resistance. Normal hardness reaches HRA 78-89, under temperature 600 ,beyond hardness of high speed steel

2.High elasticity modulus

3.High mechanical strength, compressive strength is up to 6000MN/M2

4.High density

5.Good thermal conductivity

6.Good corrosion& oxidation resistance
