As a materials science expert with extensive experience in the metallurgical industry, I have a deep understanding of the properties and applications of various metals, including steel and iron. Let's delve into the differences between these two materials.
Iron is a chemical element with the symbol Fe and atomic number 26. It is a metal in the first transition series. It is the most common element (by mass) forming the planet Earth as a whole, and it is the fourth most common element in the Earth's crust. Pure iron is relatively soft and is rarely found in nature due to its reactivity. It is a lustrous, ductile metal with very high magnetic permeability and tenacity. Iron is used in various applications, including construction, automotive, and manufacturing industries, often in the form of alloys to enhance its properties.
Steel, as mentioned, is an alloy primarily composed of iron, with the addition of carbon and other elements to improve its properties. The carbon content in steel ranges from about 0.2% to 2.1% by weight, depending on the grade of steel. This carbon content is what makes steel different from iron. The addition of carbon increases the strength and hardness of steel, making it suitable for a wide range of applications that require greater durability and resistance to deformation compared to pure iron.
The process of making steel involves the removal of impurities from iron, such as silicon, phosphorus, and excess carbon, and then alloying the refined iron with carbon and other elements like manganese, chromium, molybdenum, and nickel. This process can be done in various ways, including the basic oxygen process, electric arc furnace process, or blast furnace process.
One of the key differences between steel and iron is their strength and durability. Steel is stronger and more durable than iron due to the presence of carbon, which forms a hard interlocking structure with the iron. This makes steel an ideal material for construction, where it is used in the form of beams, plates, and reinforcing bars.
Another difference is their magnetic properties. While both iron and steel are magnetic, the presence of carbon in steel can alter its magnetic properties. Pure iron has a higher magnetic permeability than steel, but steel's magnetic properties can be tailored through the addition of other elements.
In terms of corrosion resistance, steel can be more susceptible to rusting than pure iron due to the presence of carbon, which can form galvanic cells that accelerate the corrosion process. However, many types of steel are treated or coated to improve their corrosion resistance.
Lastly, the cost and availability of steel and iron can also differ. Iron is often more readily available and less expensive than steel, but the latter's superior properties often justify its higher cost in various applications.
In summary, while both steel and iron are important metals with a wide range of applications, their properties and uses differ significantly due to the presence of carbon and other alloying elements in steel. Steel's enhanced strength, hardness, and tailored properties make it a preferred choice in many industries over pure iron.

Some common metals are titanium, copper and nickel. Steel, on the other hand, is an alloy of iron with varying amounts of carbon content (from 0.5 to 1.5 percent) [source: Merriam-Webster]. Steel, being an alloy and therefore not a pure element, is not technically a metal but a variation on one instead.
