Low/High Carbon Steels

Carbon steel, an iron-carbon alloy with a carbon content of up to 2.1% of the steel’s total weight, is one of the primary categories of steel.


• Mild or low carbon steel has a carbon content of 0.05 to 0.26 percent,
• Medium carbon steel has a carbon content of 0.29 to 0.54 percent,
• High carbon steel has a carbon content of 0.55 to 0.95 percent with very high carbon steel having a carbon content of 0.96 to 2.1 percent.


As the carbon percentage content rises, steel has the ability to become harder and stronger through heat treating; however it becomes less ductile. Regardless of the heat treatment, a higher carbon content reduces weld-ability. In carbon steels, the higher carbon content lowers the melting point.
Due to its high versatility, carbon steel has a broad range of applications and has been employed ubiquitously in a range of industries, especially in the oil, gas, and petrochemical sectors.
