The investigation of 210cr13ni7mow steel usage for iron and steel rolling mill roller

In this study, GX200Cr13Ni7MoW material was produced by casting. The material was subjected to heat treatment by exposure to four different temperatures and six different cooling intensities. Primary and secondary carbide concentration, carbide distribution, effects on carbide type were investigated by heat treatment. As a result of the wear tests, the wear resistance was determined together with the behavior of the material against the thermal shocks and the optimum heat treatment conditions were tried to be analyzed. It has been observed that increasing the cooling intensity after the homogenization heat treatment of the material as heat treatment reduces the hardness and decreasing the cooling intensity increases the hardness. It has been determined that the cause of the increase in hardness is related to the secondary carbide concentration in the structure, not from the martensitic transformation in the structure.
