Research on Test about Stress Corrosion Cracking of 16MnR Spherical Tank

摘要：

16MnR steel belongs to low-alloyed steel that is widely used to fabricate storage tank for liquefied petroleum gas (LPG). However, it has a great tendency to the problem of environmental cracking under the service condition of LPG containing wet sulfide hydrogen (H2S) surpassing the lowest allowance for steels. In order to quantitatively evaluate the cracking susceptibility on this steel in the wet H2S environment, the pre-fatigue crack M-WOL specimen stress corrosion cracking (SCC) tests in three H2S concentrations are performed under the different welding conditions and in safety performance analysis of equipment, and preventing countermeasure is proposed. The method can be extended forecasting accident in LPG SCC.
