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.

The $14.9 billion sale of iconic steelmaker US Steel to Japan’s Nippon Steel ends months of speculation over industry consolidation in a move criticized by union workers, but seen by one analyst ...
Use of wrought iron in construction has a long history (cramps made from wrought iron were used in classical antiquity). [6] The first all-wrought iron roof was apparently installed in 1837 at the Euston railway station in London. [7] Frame of the Crystal Palace. Beams and girders were made of wrought iron with I-beam cross-section. The ...
