• Difference between Iron and Steel | Iron vs Steel

    Steel is made by putting iron through a process known as smelting, where iron is extracted from the iron ore and excess oxygen is removed and the iron is combined with chemical partners such as carbon. Steel, compared to pure iron is more rust resistant and has a better weldability.

  • Metallurgy of Mo in alloy steel & iron: Hardening

    The basis of steel hardening lies in the fact, that iron exists in two crystal structures: Below 912°C and from 1394°C to its melting point iron is body centered cubic – bcc – called ferrite. In the lower temperature range ferrite is also referred to as alpha iron, in the higher temperature range as delta iron.

  • Iron Ore Pelletizing Process: An Overview | IntechOpen

    The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...

    Case-hardening is a superficial conversion of iron into steel by cementation. It is performed on small pieces of iron by enclosing them in an iron box containing burnt leather, bone-dust, or ferrocyanide of potassium, and exposing them for some hours to a red heat. The surface of the iron thus becomes perfectly hardened.
