Paper Title:
Study on the Complex Strengthening Processes of 5Cr2NiMoVSi Steel Large Hot Forging Dies
  Abstract

To meet the high requirements of fatigue strength and thermal stability for the large forging dies, the complex strengthening process tests of new high thermal stability die steel 5Cr2NiMoVSi were done. This complex strengthening process was nickel plating the RE boron penetration→ pre-cool quenching → high temperature tempering. The results show that the surface micro-hardness, high temperature oxidation resistance, thermal fatigue resistance and wear resistance of 5Cr2NiMoVSi steel can greatly be improved by these processes. It has achieved significant results for auto front axle large forging dies by using the materials and processing technology.
