Carbon steel is a ferrocarbon alloy with a carbon content of 0.0218%~2.11%, and generally contains a small amount of silicon, manganese, sulfur and phosphorus.
Advantages of high carbon steel:
1. In the annealed state, the hardness is moderate and the machinability is good.
2. Good processability, high hardness and good wear resistance can be obtained after heat treatment.
3. The smelting process is simple and the production cost is low.
The disadvantages of high carbon steel are:
1. The hardenability is low and the tempering resistance is poor. The diameter of complete quenching in water quenching is generally only 15-18 mm; During oil quenching, the maximum diameter or thickness of complete quenching is only about 6mm, and it is easy to deform and crack.
2. The thermal hardness is poor. When the working temperature of the tool is higher than 200 ℃, the hardness and wear resistance of the tool drop sharply.
