Technical service
Die vacuum heat treatment and die surface treatment(N-O,C-N,carburize and nitridation surface treatment).
Chemical heat treatment
Mold can be further strengthened If use gas nitriding or nitrocarburizing, but the nitriding temperature should not be higher than the tempering temperature, in order to ensure that the strength of the heart does not reduce, thus enhancing the service life of the mold.
Delivery condition
EF, or ESR, Hot rolled or forged, black surface or milling
Hardness: annealed to HB≤229
Feature
1) Electroslag remelting steel, the steel has a high hardenability
and thermal cracking resistance, the steel contains a higher
content of carbon and vanadium, good wear resistance, toughness is
relatively weakened, with good heat resistance.
2) High temperature with good strength and hardness, high wear
resistance and toughness, excellent comprehensive mechanical
properties and high resistance to tempering stability.
3) Good resistance to high temperature tempering performance,
hardness steady working under 600℃, dimensional accuracy stability
durability.
4) Cold and hot fatigue resistance, strong ability to resist crack.
