Difference between iron and steel
Introduction
Iron and steel are two materials widely used in different sectors of industry. Although they are both metals, there are important differences between them.
Chemical composition
Iron is a pure metal, while steel is an alloy of iron and other elements, such as carbon, manganese, nickel, chromium, among others. These additional elements give specific properties to the steel.
Carbon content
The amount of carbon present in steel is responsible for its hardness and resistance. The higher the carbon content, the harder the steel. On the other hand, iron does not have a content so tall carbon and therefore not as hard as steel.
Uses
Iron is mainly used for the manufacture of tools, machinery and construction structures. On the other hand, steel is used in the production of construction materials, automobiles, household appliances, among others.
Types of steel
- Stainless steel: It is characterized by having high resistance to corrosion.
- Carbon steel: It is the most common type of steel and is used for the construction of buildings, bridges and machinery.
- Alloy Steel: Used in applications requiring greater strength and hardness than carbon steel. Examples include the manufacturing of tools and machinery.
Conclusions
Although iron and steel are two metals widely used in different sectors of industry, there are important differences in their chemical composition and properties. While iron is a pure metal and its use is mainly limited to tools, machinery and construction, steel is an alloy with specific properties that make it more versatile and useful in different applications. Knowing the differences between iron and steel is important when making decisions regarding the materials to use in different projects.
