All steel contains iron, but it also contains carbon. ... The primary difference between iron and steel is that the former is a metal, whereas the latter is an alloy. Iron is simply a metal element that occurs naturally on Earth. In comparison, steel is a man-made alloy that's made by mixing iron and carbon together.

How can you tell the difference between iron and steel?
In addition to looking at spark pattern, watch for color. Steel will most often give off bright yellow sparks, whereas iron releases more red or orange sparks. If you do not feel confident telling the sparks apart at first, you can use a comparison.
Is iron more expensive than steel?
Cost. Cast iron is often cheaper than cast steel because of the lower material costs, energy, and labor required to produce a final product. Raw steel is costlier to purchase, and it requires more time and attention to cast.
Is iron a steel?
Steel, alloy of iron and carbon in which the carbon content ranges up to 2 percent (with a higher carbon content, the material is defined as cast iron). By far the most widely used material for building the world's infrastructure and industries, it is used to fabricate everything from sewing needles to oil tankers.
Which is heavier iron or steel?
Steel, or Iron? ... However, the density and specific gravity of steel(mild steel/low carbon steel ) and iron are the same almost (7.85 gms/cm3). Hence one is not heavier than the other. However, in case of alloy steels where lot of other metals are added as alloying elements, Steels would be heavier than iron.
Why is steel used instead of iron?
In general, due to its increased strength properties, steel is used more often than iron in large-scale industries like construction. It's more durable and won't rust as easily, and also has better tension and compression properties.
Why is steel harder than pure iron?
Something made of pure iron is softer than steel because the atoms can slip over one another. If other atoms like carbon are added, they are different from iron atoms and stop the iron atoms from sliding apart so easily. This makes the metal stronger and harder. ... These are called the properties of the steel.
