Characteristic(NKA80)
NAK80 die steel is a kind of steel that is always favored, which influences the cracking of the heat treatment of NAK80 die steel, which can be summarized as mold structure, mold material and heat treatment.
These factors influence the internal stress of heat treatment.
To prevent heat treatment cracking, all factors must be considered.
No heat treatment, excellent polishing, cutting property, good erosion.
Vacuum degassing refining treatment of steel purity.
The spheroidizing annealing is softened and the machining performance is good.
Reinforcement element vanadium, molybdenum special addition, wear resistance extremely excellent.
