Steel - Wikipedia

    Steel is an alloy of iron with typically a few percent of carbon to improve its strength and fracture resistance compared to iron. Many other additional elements may be present or added. Stainless steels that are corrosion and oxidation resistant need typically an additional 11% chromium.Because of its high tensile strength and low cost, steel is best used in buildings, infrastructure, tools ...

    In steel making the reaction between carbon and dissolved oxygen is of utmost importance. Generally pig iron contains about 4 wt% carbon. The solubility of carbon in steel is effected by the presence of impurities and alloying elements. Presence of Nb, V, Cr, Mn and W increase solubility of carbon in iron where as presence of Co, Ni, Sn and Cu decrease it. 80. •Thus solubility of carbon in ...

    Characteristics of Electric Arc Furnace .

    Electric arc furnace steelmaking mainly uses arc heat, and the temperature in the arc action zone is as high as 4000 °C. The smelting process is generally divided into a melting period, an oxidation period and a reduction period. In the furnace, not only an oxidizing atmosphere but also a reducing atmosphere can be caused, so the efficiency of dephosphorization and desulfurization is high.
