1. Mold manufacturing generally have to go through forging, cutting, heat treatment and other processes. In order to ensure the quality of mold manufacturing and reduce the production cost, the material should have good malleability, machinability, hardenability, hardenability and grindingability. It should also have small oxidation, decarburization sensitivity and quenching Deformation Cracking tendency.
Has a low hot forging deformation resistance, good plasticity, wide forging temperature range, forging cracking and precipitation of creep carbide tendency is low.
2. Annealing process
Spherical annealing temperature range is wide, the annealing hardness is low and the fluctuation range is small, the spheroidization rate is high.
Cutting the amount of large, low tool loss, low surface roughness.
4. oxidative decarburization sensitivity
High temperature heating, good resistance to oxidation, decarburization slow, not sensitive to the heating medium, resulting in pits tend to small.
