Title: Pitting corrosion of Cr-Mn-N steel. Effects of the temperature and pH of 3.5% NaCl model solution
Keywords: pitting corrosion, stainless steel, manganese, nitrogen, and sodium chloride solutions

Abstract: The pitting corrosion behaviour of Cr-Mn-N steel samples in a 3,5% model aqueous solution of NaCl has been investigated in a wide range of variations of both the bath temperature and pH. The experiments have been performed with samples of Cr14,N,Mn15 austenitic steel upon bath condition varied within the ranges: 0-80oC and 1.0-9.0 pH. Various methods (potentiodynamic, galvanostatic, optical and electron microscopy, etc.) have been employed to characterize the pitting corrosion of the steel samples. The results obtained indicated that the steel tested demonstrates a strong ability to develop pitting corrosion. The origin spots of the pitting are located mainly in the zones around the non-metallic formation of the steel (carbides, oxides and sulphides).
