Advantages and Disadvantages of Carbon Steel
Understanding the advantages and disadvantages of carbon steel, and comparing it with other alloys, allows you to select products that are suitable for specific applications and meet cost requirements.
Advantages：Carbon steel is widely used due to its specific composition and characteristics. Its advantages are quite evident, such as low cost, high strength and hardness, ease of processing for low and medium carbon steel, and excellent wear resistance for high carbon steel.
Disadvantages：The biggest disadvantage of carbon steel is its lack of corrosion resistance, which requires additional protective measures such as coating or galvanizing. High carbon steel has poor toughness and ductility and requires different heat treatment processes to achieve the desired performance. Additionally, carbon steel has low fatigue strength and is prone to fatigue failure.
Classification of Carbon Steel
We divide carbon steel into the following categories based on its carbon content. With a different carbon content, carbon steel’s performance will change, and different usage scenarios require different types of carbon steel.
Low carbon steel
- Carbon content is between 0.05% and 0.25%, with good toughness and ductility.
- Application: Building structures, automobile bodies, pipes, bolts and nuts, etc.
- ASTM specification: ASTM A36 / ASTM A53
Medium carbon steel
- Carbon content is between 0.25% and 0.60%, with a good balance of strength and toughness.
- Application: Mechanical parts, shafts, gears, pressure vessels, etc.
- ASTM specification: ASTM A105 / ASTM A29 / ASTM A106
High carbon steel
- Carbon content is between 0.60% and 1.25%, with high strength and hardness, but low toughness.
- Application: Knives, springs, drills, molds, etc.
Physical Properties of Carbon Steel
– Density: The density of carbon steel is typically about 7.85 g/cm³.
– Melting Point: The melting point of carbon steel usually ranges between 1425°C to 1540°C, depending on the carbon content.
– Thermal Conductivity: The thermal conductivity of carbon steel varies with its composition, typically between 45-60 W/m·K.
– Electrical Resistivity: The electrical resistivity of carbon steel generally ranges from 10^-7 to 10^-6 Ω·m.
Why does carbon steel need heat treatment?
We use various heat treatment methods to optimize and enhance carbon steel’s mechanical, physical, and processing properties, meeting the needs of different industrial applications. Heat treatment involves heating, holding, and cooling processes that change carbon steel’s microstructure and crystal structure to achieve the desired performance goals. Standard heat treatment methods and their purposes include:
To enhance hardness and strength, you can use quenching and tempering techniques. For increased toughness and ductility, annealing and normalizing are the way to go. If you need to relieve internal stresses, consider stress-relieving annealing. To improve machinability, opt for spheroidizing annealing. For enhanced wear resistance and fatigue strength, carburizing and nitriding are effective. Finally, if you need to adjust overall material properties, tempering is the solution.
- Annealing: Steel is slowly heated to an appropriate temperature and then slowly cooled to reduce hardness, improve ductility, and enhance machinability.
- Normalizing: Steel is heated to an appropriate temperature and then cooled in open air to refine grain size, homogenize internal structure, and enhance mechanical properties.
- Quenching: Steel is heated to an appropriate temperature and then rapidly cooled (typically in water or oil) to increase hardness and strength.
- Tempering: Steel is reheated after quenching to reduce brittleness and improve toughness.
