Treść
The aim of this study was to compare the pitting corrosion resistance of two austenitic stainless steels, AISI 304L and AISI 316Ti, which are often used for agricultural machinery building. For the corrosion experiments, animal slurry from a pig farm was used. The results obtained from electrochemical corrosion experiments were proceeded by significance tests in Statistica software. The average value of the pitting corrosion potential of AISI 304L stainless steel in the animal slurry is equal 1044.3±146.6 mVSCE whereas the average potential for AISI 316Ti SS equals 1058.4 ±28.3m mVSCE. Corrosion potential of AISI 304L SS is equal 549±80.5 mVSCE, while for AISI 316Ti SS it equals 425.9±80.5 mVSCE. The range of pitting corrosion potentials of AISI 304L SS (364 mVSCE) was over four times higher than that for AISI 316Ti SS (84 mVSCE); the minimum values of pitting corrosion potential for AISI 304L SS (779 mVSCE) was lower than that obtained for AISI 316Ti SS (1012 mVSCE). On the basis of the results it may be concluded that AISI 304L stainless steel is less resistant in case of pitting corrosion resistance than AISI 316Ti SS. For this reason, austenitic AISI 316Ti stainless steel should be used for the transportation or storage of animal slurry.
