The Science Behind the Name ‘Steel’
The Role of Iron and Carbon
The science behind steel lies in the combination of iron and carbon. By adding carbon to iron, its structural properties undergo significant changes. The precise carbon content determines various types of steel and their respective characteristics.
When carbon is added to iron, it forms a solid solution. This solution is known as austenite, which is a high-temperature phase of iron. The carbon atoms occupy the interstitial spaces between the iron atoms, causing the lattice structure to become distorted. This distortion leads to an increase in the hardness and strength of the material.
Furthermore, the presence of carbon in steel also affects its ability to be shaped and manipulated. Low carbon steel, for example, possesses excellent weldability and formability, making it suitable for construction and automotive industries. The low carbon content allows for easy deformation and shaping without sacrificing its structural integrity.
On the other hand, high carbon steel offers superior hardness, strength, and resistance to wear. The higher carbon content results in a material that is more rigid and less ductile. This makes high carbon steel ideal for tools and blades that require sharp edges and durability.
Different Types of Steel and Their Names
