What is another word for eutectoid steel?
Pronunciation: [jˈuːtɪktˌɔ͡ɪd stˈiːl] (IPA) 
Eutectoid steel is a type of steel that contains a specific composition of carbon and other alloying elements, which allow it to transform into a specific microstructure known as pearlite when cooled from a high temperature. Some synonyms for eutectoid steel include hypereutectoid steel, pearlite steel, and high carbon steel. Hypereutectoid steel has a higher carbon content than eutectoid steel and is also capable of transforming into pearlite when cooled. Pearlite steel simply refers to the microstructure that eutectoid and hypereutectoid steels form. Lastly, high carbon steel is used to describe any steel with a carbon content above 0.6%, which typically includes eutectoid and hypereutectoid steels.
