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 A review of CO2 emissions reduction technologies and low Jun 01, 2021 · As illustrated in Fig. 1, the rapid growth of steel output that had occurred before 1975 leveled off between 1975 and 2000, during which time the annual output of crude steel remained between 700 and 800 Mt [2,, , ].However, economic growth brought about by reforms and opening up led China to become the primary driver of steel output growth in the 21st century.
