As the only major steel maker not harmed during World War II, the United States iron and steel industry reached its maximum world importance during and just after World War II. In 1945, the US produced 67% of the world's pig iron, and 72% of the steel. By comparison, 2014 percentages were 2.4% of the pig iron, and 5.3% of the steel production.
Technology. Steel is an alloy composed of between 0.2 and 2.0 percent carbon, with the balance being iron. From prehistory through the creation of the blast furnace, iron was produced from iron ore as wrought iron, 99.82–100 percent Fe, and the process of making steel involved adding carbon to iron, usually in a serendipitous manner, in the forge, or via the cementation process.
The steel crisis was a recession in the global steel market during the 1973–75 recession and early 1980s recession following the post–World War II economic expansion and the 1973 oil crisis, further compounded by the 1979 oil crisis, and lasted well into the 1980s. Steel prices dropped significantly as the market became saturated with steel ...
The $14.9 billion sale of iconic steelmaker US Steel ( X) to Japan’s Nippon Steel ends months of speculation over industry consolidation in a move criticized by union workers, but seen by one ...
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, steel is one of the most commonly manufactured materials in the world. Steel is used in buildings, as concrete reinforcing rods, in bridges, infrastructure, tools, ships, trains ...
The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International . In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
European standard steel grades EN 10027-1 steel grade designation system. European standard steel grade names fall into two categories: Steel specified by purpose of use and mechanical properties. Steel specified by chemical composition. The inclusion of a letter 'G' before the code indicates the steel is specified in the form of a casting.
Carbon steel. 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 (AISI) states: or the specified maximum for any of the following elements does not exceed the percentages noted: manganese 1.65%; silicon 0.60%; copper 0.60%.
