SigmaAldrich sells pure iron in many different forms. Given that, the alloy of carbon and iron that we call steel is far more common for two reasons: iron picks up carbon during smelting (the second phase of iron production is to burn off the excess carbon) and steel is a far more useful metal than iron.
Iron typically contains small amounts of carbon, with most commercial iron containing less than 0.03% carbon. The amount of carbon present can affect the properties of the iron, with higher carbon content resulting in harder, more brittle iron.
When iron and silver are mixed together, an alloy called steel is formed. Steel is a combination of iron and carbon, with the addition of silver resulting in a stronger and more corrosion-resistant material.
The main difference between cast iron and mild steel is the carbon content. Mild steel has a lower carbon content than cast iron. This makes cast iron brittle, while mild steel is much harder.
Steel is more useful compared to Iron because it doesn't rust as easily and it is more durable than iron. Iron is more maleable than steel which makes steel more useful than iron.
I would say carbon, because it's in a lot more things.
The amount of carbon in iron is greater than 2 percent. Iron, steel is more difficult. Steel is more resistant to damage from iron.
In FCC iron, carbon atoms can occupy octahedral sites, contributing to solid solubility. BC iron has fewer octahedral sites available for carbon, limiting solid solubility. Therefore, more carbon can be accommodated in FCC iron despite having a smaller void space.
Steel is an alloy of carbon and iron. If the percentage of carbon is more than 2% then it is called cast iron.

http://encarta.msn.com/encyclopedia_761559225/iron_and_steel_manufacture.html Provides the answer. basic summary: 1. Pig Iron and Sponge Iron are the result of different production processes 2. Which results in different purities. Pig Iron has a lower purity than Sponge Iron.
