Carbon Steel Grades

Aside from carbon and iron, carbon steels contain only tiny quantities of other components. This is the most prevalent category, accounting for 90% of steel production. Carbon steel is classified into three types based on the quantity of carbon in the metal: Low Carbon Steels/Mild Steels (up to 0.3 percent carbon), Medium Carbon Steels (0.3–0.6 percent carbon), and High Carbon Steels (0.3–0.6 percent carbon) (more than 0.6 percent carbon).
