Study on Mechanical Behaviors of 16MnR Steel after Long Term Used as Liquefied Petroleum Gas Vessel

Abstract:

16MnR steel is one of C-Mn steels widely used for pressure vessels in China. Mechanical behaviors of 16MnR steel used as liquefied petroleum gas vessel for about 100,000hr have been investigated in this paper. The macrostructure, fracture toughness, fatigue-crack growth rate, and low-cycle fatigue properties of the samples have been studied in detail. Compared the results with that of GB6654-86 (one of Chinese national material standards) and other test data of 16MnR steel, it indicates that the mechanical properties of the long-term used 16MnR steel have not been degraded and aged.
