Explains what is meant by low-, medium-and high-carbon steels.Low-carbon steel, also known as mild steel. It has less than 0.30 percent carbon.Medium-carbon steel has 0.30 percent to 0.60 percent carbon.High-carbon steel has more than 0.60 percent carbon.
Compares the tensile strength, ductility and hardness of low-, medium-and high-carbon steels.Low-carbon steel – Tough. High tensile strength. Can be case hardened.Medium-carbon steel – Tough. Can be hardened and tempered.High-carbon steel – Strong but brittle. Compressive strength very high.
States the uses of low-, medium and high-carbon steels.Low-carbon steel – Generally used for industrial products: bolts, nuts, sheet, plate, tubes and machine components.Medium-carbon steel – It is generally used in application requiring higher strength such as machinery, automotive and agricultural equipment parts, rail road equipment and parts for metalworking machinery.High-carbon steel – It is generally used for parts requiring strength, hard...
