Mold Manufacturing Requirements For Material Properties

- Aug 23, 2018-

For the material performance requirements of mold manufacturing, the details are as follows:


1.Annealing process


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


2. Forgeability


It has low hot forging deformation resistance, good plasticity, wide forging temperature range, low tendency for forging cracking and precipitation of reticulated carbides.


3. Oxidation and decarburization sensitivity


When heated at high temperature, the anti-oxidation energy is good, the decarburization speed is slow, and it is not sensitive to the heating medium, and the tendency to produce pitting is small.


4. Machinability


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


5. Hardenability


Uniform and high surface hardness after quenching.


6. Hardenability


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


7. Grindability


The relative loss of the grinding wheel is small, the maximum amount of grinding without the burn is large, and it is not sensitive to the quality of the grinding wheel and the cooling condition, and it is not easy to cause abrasion and grinding crack.


8. Quenching deformation cracking tendency


The conventional quenching volume change is small, the shape is warped, the distortion is slight, and the abnormal deformation tendency is low. Conventional quenching cracking has low sensitivity and is not sensitive to quenching temperature and workpiece shape.
