- In hot rolling which is one of the plastic forming, the operation called “Tempcore Process” provides to obtain different
microstructures from the surface to the core by quenching before the cooling platform where the conventional cooling is performed
in steel profiles come out of the finish workbench which is the last stage of rolling. The purpose of this process is to obtain a
martensitic structure up to a certain thickness from the surface of the profiles to the center and tempering the martensite with the
effect of high temperature in the core. Thus, a hard and tough product is manufactured. However, it is ensured that the linearity
of the product is maintained at the platform exit. In this study, the Tempcore Process was carried out NPU and Equal Angle type
profiles of S275JR quality steel produced in Kar-demir Rolling Industry Trade Ltd. Co. and the effects of this process on the
structural form and mechanical properties of the profiles were investigated. In this context, pre- and post-Tempcore Process,
hardness measurements, tensile and impact tests were applied and the results were assessed comparatively.
