1. Malleability

It has low hot forging deformation resistance, good plasticity, wide forging temperature range, low tendency of cold forging cracking and precipitation of 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 cutting parameters, low tool wear and low surface roughness.

4. Oxidation and decarburization sensitivity

Decarburization is slow, insensitive to heating medium, and has little tendency to produce pitting.

5. Hardenability

It has uniform and high surface hardness after quenching.

6. Hardenability

After quenching, a deeper hardened layer can be obtained, which can be hardened by using a mild quenching medium.

7. Quenching deformation cracking tendency

Conventional quenching has small volume change, slight shape warping and distortion, and low tendency of abnormal deformation. Conventional quenching has low sensitivity to cracking and is insensitive to quenching temperature and workpiece shape.

8. Grindability

The relative loss of the grinding wheel is small, the amount of non burn grinding is large, and the grinding wheel is insensitive to the quality and cooling conditions of the grinding wheel, so the grinding damage and grinding cracks are not easy to occur.
