Cast iron is not a good structural material for handling tension or bending moments because of its brittleness and relatively low tensile strength compared to steel and wrought iron. However, cast iron does have good compressive strength and was successfully used for structural components that were largely in compression in well-designed ...
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.
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. Although US iron and steel output continued to grow overall through the 1950s and 1960s, the world steel industry grew much faster, and the US share of world production shrank.
He gained patents for the process in 1855 and 1856 and successfully completed the conversion of cast iron into cast steel in 1858. [21] Eventually mild steel would replace both wrought iron and cast iron as the preferred metal for construction.

Iron columns had been used in Wren's designs for the House of Commons and were used in several early 18th-century churches in London, but these supported only galleries. In the second half of the 18th century the decreasing costs of iron production allowed the construction of major pieces of iron engineering.
US Steel has agreed to be bought by Nippon Steel, Japan’s largest steelmaker, in a $14.1 billion deal. The deal marks the latest step in a gradual decline for the iconic 122-year old company ...
The basic process, the Thomas-Gilchrist process, remained in use longer, especially in Continental Europe, where iron ores were of high phosphorus content [35] and the open-hearth process was not able to remove all phosphorus; almost all inexpensive construction steel in Germany was produced with this method in the 1950s and 1960s.
