The paper presents the results of the cavitational erosion research carried out on two stainless steels intended for the manufacture of parts strongly subjected to cavitation, such as the vanes and rotors of hydraulic turbines and pumps. In accordance with the new trends, to reduce carbon below 0.1%, for both categories the carbon content was kept at the value of 0.038%. The researches are carried out in the Cavitation Erosion Research Laboratory of the Politehnica University of Timisoara, on the magnetostrictive vibrating device with a nickel tube. The behaviour and resistance to cavitation erosion are evaluated based on the comparison of curves and specific parameters with those of OH12NDL stainless steel, as a reference for the parts subjected to cavitation, as well as on the basis of microstructural images, obtained by optical and electron microscopy. The results show similarities and differences of microstructural damage between the two steels. The comparison of the specific curves and the values of the reference parameters, with those of the reference steel OH12NDL, shows that both steels can be successfully used in the manufacture of vanes and rotors of hydraulic machines.
