Period #5 Notes: Making Steel and Its Chemical …

2007-1-30 · Period #5 Notes: Making Steel and Its Chemical Composition A. MAKING STEEL 1.Iron Ore Iron is a moderately reactive metal which joins readily with non-metals such as oxygen. This is why we do not find pure iron in the Earth’s crust. Instead it is found as an ore, in which iron is chemically coined with oxygen or other non-metals.

Influence of the chemical composition on steel casting

The aluminium–calcium phase diagrams at 50 °C above the liquidus temperature of the alloys were calculated for all the proposed chemical compositions, keeping the other elements constant, as described above. As known, carbon content directly influences the steel melting temperature, ranging from 1521 °C in low-carbon steel (0.2%C) to 1486 °C in high-carbon steel, as given in Table 1.
