1. Forgeability
It has low resistance to hot forging deformation, good plasticity, wide forging temperature range, low forging cracking and low tendency to precipitate network carbide.
2. Annealing processability
The spheroidizing annealing temperature range is wide, the annealing hardness is low and the fluctuation range is small, and the spheroidizing rate is high.
3. Machinability
Large amount of cutting, low tool loss and low surface roughness.
4. Sensitivity to oxidation and decarburization
Antioxidation is good when heated at high temperature, the decarburization speed is slow, it is not sensitive to the heating medium, and the tendency to produce pitting is small.
5. Hardenability
After quenching, it has uniform and high surface hardness.
6. Hardenability
After quenching, a deeper hardened layer can be obtained, which can be hardened by using a mild quenching medium.
7. Cracking tendency of quenching deformation
Conventional quenching has small volume changes, slight warpage and distortion, and low tendency to abnormal deformation. Conventional quenching has low cracking sensitivity and is insensitive to quenching temperature and workpiece shape.
8. Grindability
The relative wear of the grinding wheel is small, the maximum amount of grinding without burns is large, and it is not sensitive to the quality of the grinding wheel and the cooling conditions, and it is not easy to cause scratches and grinding cracks.
