Mold material processing performance
May 17, 2018

1. Forgeability

It has low resistance to hot forging deformation, good plasticity, wide forging temperature range, cold cracking in forging and low tendency to precipitated carbides.

2. Annealing processability

The spheroidizing annealing temperature range is wide, the annealing hardness is low, the fluctuation range is small, and the spheroidization rate is high.

3. Machinability

Large amount of cutting, low tool loss, low surface roughness.

4. Oxidation, Decarbonization Sensitivity

Antioxidation is good at high temperature heating, the decarburization rate is slow, and it is not sensitive to the heating medium, resulting in a small pitting tendency.

5. Hardenability

Quenched with a uniform and high surface hardness.

6. Hardenability

After quenching, a deeper hardened layer can be obtained, which can be quenched with a mild quenching medium.

7. Quenching deformation cracking tendency

The conventional quenching volume changes little, the shape is warped, the distortion is slight, and the abnormal deformation tends to be low. Conventional quench cracking susceptibility is low, insensitive to quenching temperature and workpiece shape.

8. Grindability

The relative loss of the grinding wheel is small, there is no large amount of grinding limit for grinding, and it is not sensitive to the quality of the grinding wheel and the cooling conditions. It is not easy to cause grinding and grinding cracks.
