'''Steel''' is the name of an alloy created by adding an amount of up to 2 % carbon to iron.
'''Steel''' is the name of an alloy created by adding an amount of up to 2 % carbon to iron.
Modern steels often include other metals such as [[chromium]], [[molybdenum]] and [[nickel]]. Historically smiths have often accidentally created steel by forging iron with the correct carbon content, but the large scale manufacture of steel is a relatively new industry. Many famous structures such as the [[Eiffel Tower]] and [[Golden Gate Bridge]] are made of iron, as steel was too expensive to produce in large quantities. Large scale manufacturing of steel came about through [[industrial revolution|industrialization]] and the rise of [[corporation]]s, especially that of [[Andrew Carnegie]] allowing large industry to operate efficiently.

Steel has allowed great advances in the modern world due to its higher strength for low cost compared to iron. Many world-changing inventions such as the [[internal combustion]] engine would have been impractical without it, as engineers were able to build intricate parts with high strength and a wide range of working temperatures.
