“…The corrosion resistance of high-Mn steels could be improved by the addition of Al, Cr, Cu, and Mo. It is related to the tendency of these elements to form passive films on a steel surface (Ref 7,10,11).…”

The electrochemical corrosion properties of 26Mn-3Si-3Al and 27Mn-4Si-2Al austenitic steels in two different states were studied in 0.1 M H 2 SO 4 and 3.5% NaCl using potentiodynamic polarization tests. The effect of cold deformation on the microstructure and corrosion behavior of steels was analyzed. In acid solution, both steels exhibited lower corrosion resistance than in chloride solution independently on the steel state (hot-rolled, cold-worked). Cold deformation decreases the corrosion resistance, though this effect is smaller than the effect of chemical composition related to the combined Al + Si addition. All steels showed the evidence of pitting corrosion. The intensive dissolution of Fe and Mn takes place in the acid medium.

“…The corrosion behavior has been tested mainly for solutiontreated alloys so far (Ref 6,7,9,11). It is well known that microstructure and corrosion properties of austenitic steels depend also on a heat treatment applied and plastic deformation.…”

“…On the other hand, fully austenitic steels are known to be liable to aqueous corrosion [9][10][11][12], and thus a suitable corrosion protection is often necessary. In this context, hot-dip galvanizing of stated steels with standard Zn or some more advanced Zn alloyed coatings (e.g.…”

“…It was found that additions of Al, Cr, Cu and Mo improve corrosion resistance of these steels due to the passive film formation on a steel surface. Silicon addition has a negative effect on the corrosion resistance of steels [7,8]. Our previous studies [9,10] demonstrated that a presence of sulfide compounds, especially MnS inclusions, affects the corrosion resistance of steel by providing pitting sites.…”

Purpose: The aim of the paper is to compare the corrosion properties of two high-Mn austenitic steels with various Al and Si additions in 0.1M NaOH solution using a potentiodynamic method. Design/methodology/approach: The steels used for the investigation were thermomechanically rolled in 3 passes. The final thickness of about 2 mm was obtained at a temperature of 850°C. Three groups of samples were prepared: thermomechanically rolled, thermomechanically rolled and additionally annealed at 900°C for 20 min, thermomechanically rolled and additionally cold deformed in static tensile test to total elongation of 36%. Corrosion resistance of investigated steels was examined using the potentiodynamic method. The metallographic inspection of corrosion damage included scanning electron microscope observations. The chemical analyses of the corrosion pits were carried out using EDS techniques. Findings: It was found that X4MnSiAlNbTi27-4-2 and X6MnSiAlNbTi26-3-3 steels were characterized by relatively high corrosion resistance in 0.1M NaOH solution independently of their state. EDS analysis revealed that corrosion pits nucleated preferentially at nonmetallic inclusions such as MnS and AlN. Results of potentiodynamic tests showed that cold deformation had the highest influence on decreasing the corrosion resistance of investigated steels. Thermomechanically treated and supersaturated specimens showed lower values of corrosion current density and consequently less amount of corrosion damage. Research limitations/implications: To investigate in more detail the corrosion behaviour of high-manganese austenitic steels, the impedance spectroscopy investigations will be carried out. Practical implications: The knowledge of the corrosion resistance of high-Mn steels has a significant effect on their industrial application in the automotive industry. Originality/value: The corrosion resistance of two high-manganese austenitic steels with different initial microstructures was compared in alkaline solution.
