Graph of US iron and steel production, 1900–2014, data from USGS. The US iron and steel industry has paralleled the industry in other countries in technological developments. In the 1800s, the US switched from charcoal to coke in ore smelting, adopted the Bessemer process, and saw the rise of very large integrated steel mills.
The largest production of US iron ore outside the Great Lakes districts was the Birmingham, Alabama district. Sedimentary iron ore in the Red Mountain formation of Silurian age was first used to make iron in 1864. Production was small until 1881, when major steelmaking began in Birmingham. [15]
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. In the 1960s, the US became a major importer of steel, mostly from Japan.

In 2008, 2009, 2015 and 2016 output fell in the majority of steel-producing countries as a result of the global recession. In 2010 and 2017, it started to rise again. Crude steel production contracted in all regions in 2019 except in Asia and the Middle East. India is the 2nd leading producer of iron and steel industries. [citation needed]
