What material is 3Cr2W8V
This article will focus on 3Cr2W8V is what material, 3Cr2W8V is what steel this problem, before our company through product introduction, technical digest has let you have a new understanding of it, and today will be through its use of 3Cr2W8V is what material, 3Cr2W8V is what steel for a deeper understanding.
3Cr2W8V performance is excellent, its use is also quite extensive, let's take a look at the following:
3Cr2W8V is used to produce a stepped blank with the forging size (ø50mm +ø100mm) ×200mm. The wrought part material is Cr18Ni10, and the service life of the flat forging die is 1000 times.
It can be used to make hot extrusion die, when the hardness is 45~50HRC, easy to appear early fracture, service life is not high; When the hardness is 38~40HRC, it is not easy to appear early fracture, and the average service life is significantly improved.
Widely used in the temperature of 600~650℃ range of die casting die punch, die or insert, recommended hardness 48~52HRC.
When the steel is used in forging hot strength steel forgings, it can replace 5CrMnMo die steel, and the service life of the die is increased from less than 200 pieces to about 1000 pieces.
The mold made of steel is heated and quenched by gas carburizing furnace or solid carburizing agent, which is easy to cause surface carbon layer, the thickness is 0.5~2.0mm, and the mass fraction of carbon can reach 0.7%~1.0%, which is easy to cause early thermal fatigue cracking. After the surface carburization of cold working die, the main failure forms such as falling edge and brittle fracture appear.
Can be used for cavity insert material, core material. At the same time, Longtuo metal is also introduced here under the use of hardness range:
① Used for zinc alloy ZZNAL4-1, ZZNAL4-0.5, ZznAl4, the quenching hardness is 40~48HRC. ② For aluminum alloy ZL101~ZL105, ZL301, ZL302, ZL401, magnesium alloy ZM5, the quenching hardness is 20~60HRC. ③ For zinc alloy, aluminum alloy, magnesium alloy, copper alloy material die-casting, push rod material 3Cr2W8V selection of quenching hardness of 45~50HRC.
For the production of high temperature, high stress but not subject to impact load punch, concave die, such as flat forging machine bump die, insert die, copper alloy extrusion die, die casting die.
Can be used to work under the hot shear knife, etc.
Jiagang is used to make the bearing ring blank (ø31~ø33mm) øhot upsetting punch, 80~100 times /minø high-speed upsetting machine, water cooling of the punch during service. The punch hardness is 50HRC and the service life is 15,000 times, which is less than that of 4Cr5MoSiV die steel.
The average service life of the upper punch is increased from 3000 times to 9000 times, and the lower die is also increased from 5000 times to 6500 times after high temperature solution quenching and spheroidization and traditional quenching.
The aluminum alloy die casting mold is heated at (1070±10) ℃ after oil cooling, and then treated by high temperature quenching + high temperature isothermal rapid uniform spheroidization after equalizing temperature at 860℃, and then by vacuum quenching and ion nitrogen carburizing composite treatment, the service life can reach 380,000 pieces.
The mold of automobile axle sleeve is treated by high temperature normalizing + high temperature annealing + quenching + precooling + tempering, and the hardness is 38HRC.
See here, whether you have understood the real answer to what material 3Cr2W8V is.
