What is steel?
Steel is an alloy material composed of iron and carbon as well as other alloying elements. It is a very common and important metallic material with many uses, including construction, machine manufacturing, automobile manufacturing, aerospace, electronic equipment, and many other fields. The main component of steel is iron, usually more than 99%, while the carbon content usually ranges from 0.2% to 2.1%, depending on the type of steel and its use.
By adjusting the content of alloying elements and the manufacturing process, various types of steel can be obtained with different properties such as strength, hardness, corrosion resistance, etc. This makes steel a very versatile material that can be used in a variety of different projects and applications.
