Tool and die Machining Process Performance
The manufacturing of the mouldgenerally goes through several processes such as forging, cutting, and heat treatment. In order to ensure the manufacturing quality of the mouldand reduce the production cost, the material should have good forgeability, cutting workability, hardenability, hardenability and grindability; it should also have small oxidation, decarburization sensitivity and quenching Deformation and cracking tendency.
It has low hot forging deformation resistance, good plasticity, wide forging temperature range, low forging cracking and cold carbide precipitation tendency.
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.
Large amount of cutting, low tool loss and low surface roughness.
4. Sensitivity to oxidation and decarburization
The anti-oxidation performance 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.
After quenching, it has uniform and high surface hardness.
After quenching, a deeper hardened layer can be obtained, which can be hardened by using a mild quenching medium.
7. Cracking tendency during quenching deformation
Conventional quenching has small volume change, slight warpage and distortion, and low tendency to abnormal deformation. The cracking sensitivity of conventional quenching is low, and it is not sensitive to the quenching temperature and the shape of the workpiece.
The relative wear of the grinding wheel is small, and the maximum amount of grinding without burns is large. 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.
