    <ns1:description language="en">Experimental research of corrosion behavior and resistance of ferritic (EN
1.4713/X10CrAlSi7) steel in nitric acid with the concentration of 0.50 moldm-3 is presented in this
paper. The corrosion characteristics of the steel were tested using the following electrochemical
methods: open circuit potential (OCP), extrapolation of the polarization curve in the Tafel region,
and linear polarization resistance (LPR). Additionally, the weight-loss method (with a duration of 10
days) was used and compared with the polarization methods. The measurement results have shown
excellent agreement between electrochemical methods with the differences in determining corrosion
current within ±10%. Although it looks like a significant difference, it can be considered a good result
since that is the usual difference between these methods because they determine the corrosion rates
at different times of the samples exposal in corrosion environment. The general conclusion is that
examined heat-resistant stainless steel does not provide high corrosion resistance in the 0.5M nitric
acid. This research was performed considering assessing the suitability of the material for renewable
energy equipment like landfill gas flares (LGF) and additional equipment for that system. Although
the 1.4713 steel has good mechanical and thermal characteristics, it requires additional corrosion
protection for use in such working conditions.</ns1:description>
    <ns1:description language="sr">U ovom radu su predstavljena eksperimentalna istraživanja korozionog ponašanja i otpornosti
feritnog (EN 1.4713/X10CrAlSi7) čelika u azotnoj kiselini koncentracije 0,50 moldm-3. Korozione
karakteristike ovog čelika ispitane su sledećim elektrohemijskim metodama: potencijal otvorenog
kola (POK), ekstrapolacija polarizacione krive u Tafelovom regionu i metoda linearnog polarizacionog
otpora (LPO). Pored toga, korišćena je metoda gubitka mase (u trajanju od 10 dana) i
upoređena je sa metodama polarizacije. Rezultati merenja pokazali su izvrsno međusobno slaganje
elektrohemijskih metoda, sa razlikama u određenoj korozionoj struji u okviru ± 10%. Metoda gubitka
mase pokazala je oko polovine vrednosti brzine korozije u odnosu na ove elektrohemijske metode.
Iako izgleda kao značajna razlika, može se smatrati dobrim rezultatom, jer je to uobičajena razlika
između ovih metoda; jer one određuju brzinu korozije u različito vreme izlaganja uzoraka u korozivnom
okruženju. Opšti zaključak je da ispitivani nerđajući čelik otporan na visoke temperature ne
pruža visoku otpornost na koroziju u 0,5M rastvoru azotne kiseline. Ovo istraživanje je izvedeno
uzimajući u obzir procenu pogodnosti materijala za opremu za obnovljive izvore energije, poput
baklji za odlagalište gasa (LGF) i dodatnu opremu tog sistema. Iako čelik 1.4713 ima dobre mehaničke
i toplotne karakteristike, za upotrebu u takvim radnim uslovima potrebna je dodatna zaštita
od korozije.</ns1:description>
