WebThe (strongly simplified) TTT diagrams show not only what you will get, but also that by alloying one can indeed move the pearlite / bainite noses to the right, i.e. to larger times as claimed above. These curves once more, contain a hell of a lot of extremely useful information. They are complex - yes! WebSince the compositions of most cast irons are around the eutectic point of the iron-carbon system, the melting temperatures closely correlate, usually ranging from 1,150 to 1,200 °C (2,102 to 2,192 °F), which is about 300 °C (572 °F) lower than the melting point of pure iron.

WebJun 30, 2024 · In contrast to cast iron, steels generally have a relatively low carbon content (< 2 %) and are therefore typical representatives of the metastable system. A microstructure solidified according to the metastable system basically consists of iron (Fe) and cementite (Fe 3 C). This applies in particular to steels!
