Carbon steel is commonly used across many industries. It is affordable while still providing excellent mechanical properties. Carbon steel is typically composed of 0.05% to about 2.0% carbon measured by weight, along with iron and trace amounts of other elements. There are many types of carbon steel that can be easily machined, but there are also many that may prove to be difficult. Grades of lower carbon steel such as C1010 and C1018 have good machinability. Alternatively, carbon steel with higher amounts of carbon such as C1141 and C1144 can also be machined without difficulty due to the sulfur that is added to their chemical composition.
