Die manufacturers generally have to go through forging, cutting, heat treatment and other processes. In order to ensure the manufacturing quality of the die and reduce the production cost, the material should have good malleability, cutting machinability, hardenability, hardenability and grindability, and should also have small oxidation, decarbonization sensitivity and quenching deformation cracking tendency.
It has low resistance to hot forging deformation, good plasticity, wide forging temperature range, low tendency of cold cracking and precipitation of network carbides.
2. Annealing Processing
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 cutting parameters, low tool wear, low surface roughness.
4. Sensitivity of oxidation and decarbonization
When heated at high temperature, it has good antioxidant capacity, slow decarbonization speed, insensitive to heating medium and little tendency to produce pitting.
After quenching, it has uniform and high surface hardness.
After quenching, a deeper hardening layer can be obtained, and it can be hardened by using a mild quenching medium.
7. Quenching Deformation Cracking Tendency
The volume change of conventional quenching is small, the shape warpage and distortion are slight, and the tendency of abnormal deformation is low. Conventional quenching has low cracking sensitivity and is insensitive to quenching temperature and workpiece shape.
The relative wear of grinding wheel is small, the amount of non-burn grinding is large, it is insensitive to the quality of grinding wheel and cooling conditions, and it is not easy to cause grinding damage and grinding cracks.
