Carbon usually increases hardenability of steel, but beyond eutectoid point (0.8%C), it decreases. Why?

As we know that beyond eutectoid point there is a formation of proeutectoid cementite in hypereutectoid steel. This will acts as a nucleating site for pearlite formation rather than the martensite. So as a result hardenability decreases.

See lessThank you madam,reason makes sense.

See lessMay be due to the increase in carbon content could leads to increase in the brittleness of steel. Because more than 0.8% C steels are having high possibility of becoming martensite phase.
