CORROSION BEHAVIOUR OF SELECTED HIGH MANGANESE AUSTENITIC STEELS

Popis výsledku v původním jazyce

High-manganese steels (20-30% Mn, suitable for cars) have higher toughness and ductility compared to unalloyed structural steels at comparable strength properties. The corrosion resistance of these steels can be reduced by a high content of manganese which is not electrochemically noble element. In this paper are compared the results of corrosion tests of TWIP (X70Mn22) and TRIPLEX (X100MnAl28-12) steels in rolled and annealed state with structural carbon steel C17 (CSN 411375). The cyclic potentiodynamic method for pitting sensitivity in neutral NaCl solution and potentiodynamic polarization method for assessing the resistance to uniform corrosion in acidic conditions (sulfuric acid water solution) were used. Exposition standard salt spray test, gravimetric method as well as microscopic observations of structure and corrosion were also applied. Based on the exposure tests and measurements the average corrosion rates (non-uniform and pitting) were determined and the ranking of steel re
