comparative analysis of electrical and thermalinductive melting in steelworks
SteelWikipedia
Steel is an alloy of iron with typically a few tenths of a percent of carbon to improve its strength and fracture resistance compared to iron. Many other 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 used in buildings infrastructure tools
