服役多年的16MnR材料性能退化研究

Study on performance degradation of 16MnR used for thirteen years.

对服役１３年的１６ＭｎＲ制造的液化石油气贮罐进行解剖，测定了罐体母材的常规力学性能和断裂疲劳性能，与国标和已测定的１６ＭｎＲ新材料进行分析比较，发现使用１３年之久的低合金钢１６ＭｎＲ性能基本没有发生退化。

The conventional mechanical performance and fracture fatigue performance of a liquid petroleum storage tank of 16MnR used for thirteen years were measured with a dissection.It was found that the performance did not degrade in comparison with GB and the performance measured of new 16MnR.
