WebHypoeutectoid steels too need additional heating over eutectoid steel to get homogeneous austenite. The Fe-Fe 3 C diagram illustrates that in hypoeutectoid steels, A 3 temperature decreases as the carbon content of the steel is increased to 0.77%, i.e., the rate of austenitisation increases due to increasing amount of pearlite present in structure.
