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.
The National Tube Works, operated by the National Tube Company, was a large steel tube foundry located in McKeesport, Pennsylvania. The tube works employed a large amount of the town and were a symbol of the town itself. Its closure in 1987 severely impacted the town's economy and contributed towards its decline.
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.
Steel production by countries. United States steel production faced a steep decline in the 1970s. 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.

Abbey Steelworks was planned in 1947, but today is correctly termed Tata Steel Strip Products UK Port Talbot Works.It is believed to be named after the Cistercian Margam Abbey that used to be on the site – a small amount of the original building still stands (protected) within the site that survived the dissolution of the monasteries.
Nowadays, the steel industry is on the edge of a major technological evolution to deal with the huge amounts of CO 2 produced in the conventional steelmaking process. The use of blast furnaces and basic oxygen furnace produces around 1.8 ton of CO 2 per ton of steel produced. [ 6 ]
During the manufacturing process the mother tube goes through a series of shaping stands which form the round HSS (mother tube) into the final square or rectangular shape. Most American manufacturers adhere to the ASTM A500 or newly adopted ASTM A1085 standards, while Canadian manufacturers follow both ASTM A500 and CSA G40.21.
