Carbon Content Impact on Steel Properties

Increasing the percentage of carbon in steel significantly alters its mechanical properties. While carbon enhances certain characteristics, it diminishes others.

Steel Properties Affected by Carbon

Carbon is a crucial alloying element in steel. Its concentration affects the balance between strength, hardness, and ductility.

• Strength & Hardness: Adding carbon generally increases the strength and hardness of steel.
• Ductility & Brittleness: Conversely, as carbon content rises, the ductility (the ability to deform without fracturing) decreases, and the steel becomes more prone to brittleness (fracturing easily under stress).

Therefore, a percentage increase in carbon in steel leads to a decrease in its ductility.
