Heat Treatment:

该钢退火软化较困难,一般采用等温球化退火。

退火工艺:

加热温度为850~870度,保温4~6H,等温温度为760度,保温6~8H,炉冷到600度以下出炉空冷,硬度为229HBW。

淬火加热温度为960~980度,油冷或空冷,硬度62HRC;回火温度为280~300度,回火3次,每次1H。回火硬度60~62HRC。

采用高温淬火、高温回火(1030度淬火,520度回火三次)的模具钢具有高耐磨性和热硬性。采用较低温度淬火、较低温度回火(900~980度淬火,200~290度回火)的模具具有良好的强韧性。

It is difficult to soften the steel after annealing, and isothermal spheroidizing annealing is generally used.

Annealing process:

The heating temperature is 850 ~ 870 ℃, the holding time is 4 ~ 6h, the isothermal temperature is 760 ℃, the holding time is 6 ~ 8h, the furnace is cooled to below 600 ℃, the furnace is discharged for air cooling, and the hardness is 229hbw.

The quenching heating temperature is 960 ~ 980 ℃, oil cooling or air cooling, and the hardness is 62Hrc; The tempering temperature is 280 ~ 300 ℃, tempering for 3 times, 1H each time. Tempering hardness: 60 ~ 62Hrc.

The die steel with high temperature quenching and high temperature tempering (1030 degree quenching and 520 degree tempering for three times) has high wear resistance and thermal hardness. The die with lower temperature quenching and lower temperature tempering (900 ~ 980 ℃ quenching and 200 ~ 290 ℃ tempering) has good strength and toughness.

Features and Application:

Cr4W2MoV钢的主要特点是共晶碳化物颗粒细小,分布均匀,具有较高的淬透性和淬硬性,并具有较好的耐磨性和尺寸稳定性。

该钢热加工温度范围窄,变形抗力较大。经实际使用证明Cr4W2MoV钢是性能良好的冷作模具钢,可用来制造各种冲模、冷镦模、落料模、冷挤压凹模及挫丝板等工模具。

The main characteristics of Cr4W2MoV steel are fine eutectic carbide particles, uniform distribution, high hardenability and hardenability, and good wear resistance and dimensional stability.

The steel has narrow hot working temperature range and large deformation resistance. The practical application shows that Cr4W2MoV steel is a cold working die steel with good performance. It can be used to manufacture all kinds of dies, cold upsetting dies, blanking dies, cold extrusion concave dies, filigree plates and other tools and dies.
