Metals are widely used in construction. Out of which, iron is the most popular metal employed. Based on the carbon content, iron can be classified as:

  1. Wrought Iron
  2. Steel
  3. Cast Iron or Pig Iron
Wrought iron has a carbon content of less than 1.15%. Steel has a carbon content between 0.15 and 1.5%. Cast iron has a carbon content between 1.5% and 4%.

Steel is derived from pig iron by reducing the iron content in a bressemer converter in the steel mills.

Based on the carbon content, steel can be classified as:
  1. Mild Steel
  2. Medium Carbon steel
  3. High carbon steel


 
Mild steel has a carbon content from .15% to 0.3%.Medium carbon steel has a carbon content from 0.3% to 0.8%.High carbon steel has a carbon content from 0.8% to 1.5%.

Increasing the carbon content will increase the strength and hardness. But, high carbon content will result in a decrease of ductility. 

Mild steel is used more compared to high carbon steel in construction. Alloy steel is the steel made by adding desired properties by alloying other than adding carbon.

Based on the application, Mild Steel can be classified into:
  1. Reinforcing Steel
  2. Structural Steel
