The density of steel is between 7480 and 8000 kilograms per cubic meter. The reason the density of steel is given as a range rather than a singular number is because steel is an alloy containing both iron and carbon atoms.
The percentage of each element used in steel varies and impacts the density of the metal. Alloys with higher amounts of iron have a higher density because iron is more dense than carbon. Steel is a metal commonly used in the construction industry due to its tensile strength and hardness. It is also used to make tools, machines, vehicles and weapons.
