| Description
| - 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 resistance was established. On the basis of the polarization test in chloride solutions there were found much higher values of corrosion rate of X70Mn22 (TWIP) steel compared with X100MnAl28-12 (TRIPLEX) one, while a positive effect of aluminum for corrosion resistance was confirmed. In the sulfuric acid solution slightly lower resistance TWIP steels compared with TRIPLEX was measured, but both Mn steels have unacceptably high corrosion rate
