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.

See lessBeyond 0.8% C The formation phases will change that is pearlite and cementite these two phase higher hardness but less hardenability reason is less formation of ferrite phase
Beyond 0.8% C The formation phases will change that is pearlite and cementite these two phase higher hardness but less hardenability
reason is less formation of ferrite phase
