iron steel flow diagram

Steel - Wikipedia

Steel is an alloy made up of iron with typically a few tenths of a percent of carbon to improve its strength and fracture resistance compared to other forms of 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 ...
