Abstract The cavitation corrosion behavior of 1Cr18Mn14N stainless steel in HCl solution was investigated by using a magnetostrictive-induced cavitation facility. The micrographs of damaged surfaces were observed by scanning electron microscope( SEM) and the polarization curves under quiescent and cavitating condition were measured. The influence of corrosion and hydrogen on cavitation damage was analyzed. The results showed that the resistance to cavitation corrosion of 1Cr18Mn14N stainless steel in 0.1 mol/L HCl solution was higher than that of 0Cr13Ni5Mo stainless steel. Conversely, the resistance was much worse than that of 0Cr13Ni5Mo stainless steel in 0.5mol/L HCl, because the combined action of anodic dissolution and hydrogen embrittlement accelerated the initiation and propagation of the crack on the surface of 1Cr18Mn14N and then facilitated the removal of massive materials by the propagation and connection of cracks.
