The article provides the results of investigation of the way various types of thermal treatment affect the microstructure parameters and mechanical properties of grade 76HF (R65) carbon rail steels produced by Russian and Japanese manufacturers and used for the production of R65 rails. We determined the optimal heat treatment conditions to provide an increased microhardness and wear resistance of rail steel.
