Carbon Steel

Definition - What does Carbon Steel mean?

Carbon steel is a common type of steel that is an alloy of iron and carbon. It has a higher carbon content, lower melting point and greater durability compared to stainless steel.

Carbon steel is the most widely used engineering and construction material for industrial applications on a large scale, including marine structures, power plants, transportation, chemical processing and petroleum production and refining.

Corrosionpedia explains Carbon Steel

Carbon steel has high tensile strength and hardness but is significantly more prone to corrosion.

Carbon steel may contain a range of carbon concentrations from 0.01% to 1.5% in a given alloy. This variation results in different types of carbon steel:

  • Low carbon or mild steel: 0.25% carbon concentration
  • Medium carbon steel: 0.25% to 0.70% carbon concentration
  • High carbon steel: 0.7% to 1.5% carbon concentration
