Carbon Steel is a steel alloy where carbon is the main alloying element. Typically, Carbon Steel contains up to 2.0% carbon by weight, along with a variety of other alloying elements, such as manganese or silicon, depending on the desired attributes and physical properties.
Carbon steel can be grouped into 3 categories:
Low Carbon Steel (also known as Mild Steel),
Low Carbon Steel typically contains between 0.04% to 0.30% carbon content.
Medium Carbon Steel
Medium Carbon Steel typically contains between 0.31% to 0.60% Carbon and is stronger than low carbon steel, but more difficult to form, weld and cut.
High Carbon Steel
High Carbon Steel (also known as Carbon Tool Steel) typically contains between 0.61% and 1.50% carbon, and is very difficult to cut, bend and weld.
