The main features of cemented carbide roll ring are as follows:
High hardness, good wear resistance -- the hardness at room temperature can reach HRA78~95, the red hardness at high temperature is good, it exceeds high-speed steel at 600oC and carbon steel at 1000oC.
High mechanical strength - compressive strength up to 6000MN /m2, 900oC bending strength can be more than 1000MN/m2.
High modulus of elasticity -- good rigidity at room temperature, no obvious plastic deformation.Its young's modulus is 2-3 times that of steel.
