Eutectoid transformation normally in plain carbon steel requires 0.8% carbon and 768o C temperature. This is one of the very important and widely used solid-state transformations converting austenite into pearlite upon cooling. With the addition of austenite stabilizer elements, ferrite stabilizer elements, and carbide forming elements, a eutectoid point on the phase diagram changes position not only on the temperature scale but also on the carbon scale. With austenite stabilizers, austenite stabilizes at a lower temperature as well which indicates eutectoid transformation will occur at lower temperatures. While carbide forming elements will have an affinity towards carbon thereby altering the required carbon percentage for eutectoid reaction. This alters the carbon percentage for eutectoid transformation.
