| Abstract: | The lapse question of steel products is analysed and discussed through testing data of chemical composition, microstructure, inclusion, heat treatment, macro examination etc. It is shown that the cause of lapse formation is a kind factor or a few factors together. Based on these, some measures of protection and improvement are proposed. |

| Keywords: | lapse analysis chemical composition microstructure heat treatment |
