文摘The paper introduced the 5 CrMnMo steel, including the chemical composition, the heat treatment technology, the forging die working condition, and the invalidation form (such as the cavity arris wear, the cavity subsidence, the cold and the heat fatigue crackle). Then gave some precautions for prolonging the mould life by improving the heat treatment technology.
