Steel is an alloy of iron and carbon with improved strength and fracture resistance compared to other forms of iron. Because of its high tensile strength and low cost ...
The properties of steel depend on its microstructure: the arrangement of different phases, some harder, some with greater ductility. At the atomic level, the four phases of auto steel include martensite (the hardest yet most brittle), bainite (less hard), ferrite (more ductile), and austenite (the most ductile). The phases are arranged by ...
Steel mill with two arc furnaces. Steelmaking is the process of producing steel from iron ore and/or scrap.Steel has been made for millennia, and was commercialized on a massive scale in the 1850s and 1860s, using the Bessemer and Siemens-Martin processes.
Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an iron-based alloy containing a minimum level of chromium that is resistant to rusting and corrosion. Stainless steel's resistance to corrosion results from the 10.5%, or more, chromium content which forms a passive film that can protect the material ...
Structural steel is a category of steel used for making construction materials in a variety of shapes.
Nippon Steel was standing firm on its proposed $15 billion acquisition of U.S. Steel, Chief Executive Eiji Hashimoto said Tuesday after President Joe Biden’s blocked the top Japanese steelmaker ...
The decision to block U.S. Steel's acquisition by Nippon Steel is the perfect coda to President Joe Biden's political career.. By intervening in the private business affairs of the two companies ...
Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. The definition of carbon steel from the American Iron and Steel Institute ...
