Description
5CrNiMoV is a high wear resistance hot forging mold steel. Good toughness, high strength and good wear resistance. The mold steel produced by electric arc furnace (EAF) + refining (LT) + vacuum (VD) has high purity and good performance.
5CrNiMoV Chemical Composition
| C | Si | Mn | P | S | Cr | Mo | Ni | V |
| 0.5~0.6 | ≤0.35 | 0.5~0.8 | ≤0.03 | ≤0.03 | 0.8~1.1 | 0.35~0.5 | 1.4~1.8 | 0.1~0.3 |
Heat Treatment
Annealing: 760-780℃ Hardness: 197-241HB
Quenching temperature: 890-910℃, oil cooling, hardness: 61.5HRC
Tempering temperature: 420-550℃, tempering twice
Hardness: 38-47HRC
This steel can be hardened when cooled in the air, and is easy to form white spots, so it should be cooled slowly after forging.
For large forgings, it must be placed in a furnace at 600°C, and after the temperature is consistent, slowly cooled to 150-200°C, and then cooled in air.
For larger forgings, it is recommended to immediately perform tempering and heating after cooling to 150-200°C.
Features and Application
Generally used to make various large and medium forging dies.
