| Abstract: | By utilizing the structural characteristics of type 431 stainless steel, which reveals a wide range of strength as well as corrosion resistance with tempering after quenching, its susceptibility to erosion-corrosion was investigated as a function of tempering temperature. Tests were conducted under a vibratory cavitation condition of 6.5 kHz with a double amplitude of 75 /gmm or of 20 kHz and 50 μm in cavitation media of 3% NaCl solution, 0.1N HCl and 0.1N H2SO4 at 22°C. As a preliminary investigation, the mechanical properties and corrosion resistance, in the same solutions as the cavitation media, were also determined as a function of the tempering temperature.The results indicated that the susceptibility to erosion-corrosion depended predominantly upon the mechanical strength but there were some exceptions for which attention should be paid to the corrosion resistance. |
