What Is Steel Made Of?

Steel is one of the most versatile materials on the planet and has many uses in everyday life. It is a strong and durable metal used for construction and manufacturing, among other things. But what exactly is steel made of?

Iron and Carbon

Steel is generally composed of iron with small amounts of carbon (around 0.2-2%). In some cases, other elements such as manganese, chromium, and vanadium are added to create different types of steel with different properties or control costs. The proportion between these elements can vary greatly depending on the steel produced.

Steel begins its life as iron ore which must first be mined and processed before it can be smelted into molten form in furnaces at temperatures exceeding 2000°C (3632°F). During the smelting process, oxygen or air may be injected into the furnace alongside fuel such as coal or natural gas to strip out the impurities from the ore. This produces a liquid metal known as “pig iron” which then needs to be refined further to become usable steel.

During this process, additional elements such as manganese, chromium and vanadium are added as necessary to produce specific grades of steel for different applications. The molten metal can then be poured into moulds where it hardens and cools into solid shapes, such as flat sheets or rods ready for use in construction and manufacturing projects.

The Unique Properties of Steel

The mixture of iron, carbon, and other alloying elements gives steel its unique properties making it one of the most robust materials available for everyday tasks; its strength makes it ideal for building bridges, skyscrapers, vehicles, and tools while its flexibility allows it to be formed into a variety of shapes without breaking or bending easily.

Overall, resilient steel plays an important role in our day-to-day lives. Understanding what steel is made up of helps us appreciate just how valuable this metal is – no matter what application it’s used for!
