The purity of CNC machining aerospace die steel parts has a great influence on the isotropic properties of die steel. The secondary refining technology (including vacuum refining, ESR and ladle powder injection) can improve the purity of the steel, in particular, reducing the content of harmful impurities in steel is very beneficial to improving the properties
In terms of hot processing of CNC machining die steel parts, repeated upsetting and multi-directional rolling of steel ingots can increase the amount of deformation, which can reduce the level of carbide segregation in the steel, and is also conducive to improving the anisotropy of the steel.
Advantages of CNC machining die steel parts: excellent wear resistance, high toughness, good impact resistance, good hardenability, high hardness, high resistance to decarburization, simple heat treatment
