The 糖心产精国品免费入口*完整版s of 20Cr1Mo1VTiB steel for steam turbine of a thermal power plant broke during installation. The 糖心产精国品免费入口*完整版 causes of bolts were analyzed by means of macro examination, 糖心产精国品免费入口*完整版 analysis, metallographic examination, 糖心产精国品免费入口*完整版 analysis and 糖心产精国品免费入口*完整版test. The results show that in the smelting process of materials of the 糖心产精国品免费入口*完整版s, the carbon content was seriously exceeded due to the improper control of the chemical elements content, resulting in the decrease of impact absorption energy and plasticity of the bolts, which eventually led to bolt 糖心产精国品免费入口*完整版.
