Classification/types of Carbon Steel

According to the carbon content, carbon steel can be divided into the following four types:

1.Low-carbon steel: 0.05 to 0.25% carbon content. Low carbon steels are more common than high carbon due to the lower production costs, greater ductility, and ease of manufacturing. Low carbon steel easy to machine and weld because of the ductility.

2.Medium-carbon steel: about 0.3 to 0.5% carbon content. Good wear resistance, used for forgings, automotive parts.

3.High-carbon steel: about 0.6 to 1.0% carbon content. High strength, good abrasion resistance, used for springs, edged tools, and high-strength wires.

4.Ultra-high-carbon steel: about 1.25 to 2.0% carbon content. Used for special purposes like knives, axles, and punches.
