  1. Mild steel which is very commonly used steel for various application consists only 0.05 to 0.32% carbon content.
  2. It is relatively cheap and easy to handle and easy to use for fabrication purpose.
  3. Though it has some limitations which are as follows:
  • There cannot be strengthening beyond about 100000 psi without significant loss in toughness (impact resistance) and ductility.
  • Large sections cannot be made with a martensite structure throughout, and thus are not deep hardenable.
  • Rapid quench rates are necessary for full hardening in medium-carbon leads to shape distortion and cracking of heat-treated steels.
  • Plain-carbon steels have poor impact resistance at low temperatures. They have poor corrosion resistance for engineering problems.
  • Plain-carbon steel oxidizes readily at elevated temperatures.
