Early 糖心产精国品免费入口*完整版 failure of S136 steel molds occurred during its use. The failure causes of the molds were analyzed by means of macro observation, chemical composition analysis, scanning electron microscopy, energy spectrum analysis and metallographic examination. The results show that the main reason for the 糖心产精国品免费入口*完整版 of large pieces mold was that the excessive 糖心产精国品免费入口*完整版 in the 糖心产精国品免费入口*完整版 of the inner hole caused serious quenching and modification layer on the edge of the inner hole, which resulted in the surface tension stress 糖心产精国品免费入口*完整版. At the same time, there were 糖心产精国品免费入口*完整版s in the matrix structure, which can reduce the strength and toughness of the material, increase the tendency of 糖心产精国品免费入口*完整版 in the inner hole of the mold and accelerate the process of crack propagation. The main reason for the 糖心产精国品免费入口*完整版 of small pieces mold was that the chamfer of the groove was too small and the 糖心产精国品免费入口*完整版increased remarkably. Under the action of working load, 糖心产精国品免费入口*完整版and 糖心产精国品免费入口*完整版 were formed.
