What are the advantages and disadvantages of high carbon steel

After proper heat treatment or cold drawing hardening, high carbon steel has high strength and hardness, high elastic limit and fatigue limit, and the cutting performance is acceptable, but the welding performance and cold plastic deformation ability are poor. High-carbon steel is mainly used to make springs and wear-resistant parts.

Advantages:

1. High hardness (HRC60-65) and good wear resistance can be obtained after heat treatment.

2. Moderate hardness in annealed state, with good machinability.

3. The raw materials are easily available and the production cost is low.

Disadvantages:

1. Poor thermal hardness. When the working temperature of the tool is greater than 200°C, its hardness and wear resistance drop sharply.

2. Low hardenability. The diameter of fully quenched during water quenching is generally only 15-18mm; the maximum diameter or thickness of fully quenched during oil quenching is only about 6mm, and it is easy to deform and crack.
