Hello from Turkey. The critical cooling rate used in the field of heat treatment is related to hardenability. If the TTT diagram of a steel is close to the right side, a high hardness microstructure can be achieved even at slower critical cooling rates. This depends completely on the chemical composition of the steels (%C, %Ni,%Mo,%Mn,%Cr)
