STUDY OF RESISTANCE TO CAVITATION TO MARTENSITIC
STAINLESS STEEL WITH 12 % CHROM USED IN
MANUFACTURING HYDRAULIC MACHINERY BLADES
Paper analyses the cavitations erosion for stainless steel with 12 %
chromium and 6 % nickel content. The experimental researches were
undertaken in the Cavitations Laboratory of the Timişoara Polytechnic
University using a vibratory facility respecting the conditions of the ASTM G32-
2006 Standard.
The steel behaviour was evaluated both on the ground of
microstructure erosion (through optic and electronic microscopy) and by
comparisons with other reference steel, with 18 % chrome and 10 % nickel,
which was use in Romania and other countries for manufacturing turbine
blades.
