What is the Difference Between Steel and Iron?

The main difference between steel and iron lies in their composition and properties. Iron is a naturally occurring element, while steel is an alloy of iron and carbon. Here are the key differences between steel and iron:

• Composition: Iron is a pure element, while steel is an alloy of iron and carbon. Steel can also contain other elements such as manganese, silicon, phosphorus, and sulfur.
• Strength: Steel is stronger than iron in terms of yield and tensile strength, making it more durable and less likely to crack, warp, twist, rot, or split.
• Toughness: Steel is significantly tougher than iron, which contributes to its durability and resistance to damage.
• Corrosion Resistance: Apart from stainless and galvanized steel, all steels are susceptible to corrosion. However, they don't corrode as readily as iron due to their non-porous nature.
• Applications: Steel is a superior material for various industries due to its strength, toughness, and lighter weight compared to iron. It is used in the production of tools, aerospace components, medical equipment, residential applications, and cookware.

In summary, steel is an alloy of iron and carbon that is stronger, tougher, and more resistant to corrosion than iron. It is widely used in various industries due to its superior properties and versatility.

Comparative Table: Steel vs Iron

Here is a table comparing the differences between steel and iron:

As seen in the table, the main difference between steel and iron lies in their composition and properties. Iron is an element, while steel is an alloy made from iron and carbon. Steel has a modern and industrial appearance, while iron has a classic, rustic look. In terms of durability and weather resistance, iron is stronger and more weather-resistant than steel, making it suitable for outdoor use. However, iron furniture can be heavy and difficult to move, whereas steel furniture is lightweight and easy to move around.
