Critical temperature in iron carbon diagram
WebMar 5, 2024 · In contrast, for black heart malleable cast iron, carbon in a cast iron obtained by cooling after casting is present in cementite form (Fe 3 C), which is a compound of carbon with iron. Thereafter, the cast iron is heated to and held at a temperature of 720° C. or higher, so that the cementite is decomposed to precipitate graphite.
