Abstract As the transportation equipment of the large marine ship, cracks were found on the adapter strip of one transfer vehicle during use. The material of the adapter strip was 304 stainless steel. In order to find out the causes for the cracking of the adapter strip, the macro analysis, micro analysis, chemical composition, mechanical properties and metallographic analysis of the adapter strip were carried out by scanning electron microscope, direct reading spectrum, energy spectrometer, metallographic microscope, universal material testing machine and Brinell hardness tester. Through the stress corrosion test, the causes for the crackng of the adapter strip were verified. The results showed that the unqualified material of the adapter strip of the transport vehicle was the main reason for the cracking, and the intergranular corrosion and stress corrosion in the marine environment were the inducing factor for the craking of the adapter strip. Through the vibration aging treatment of the frame and the use of 316L stainless steel with better corrosion resistance, the occurrence of similar incidents could be effectively avoided.
