Influence of copper and tin addition on pitting corrosion behaviour of AISI 304 Strainless Steel
Description
The influence of copper and tin addition on the pitting corrosion resistance of AISI 304 stainless steel in 3.5% NaCl at 20 degree centigrade has been studied using potenciodinamic and cyclic polarization. From that study the effect of alloying elements (Cu and Sn) in the corrosion, pitting and re passivation potentials were determined. The effect of copper and tin on the critical pitting temperature (CPT) was determined by icorr-time-temperature curves. The influence of these alloying elements in FeCl3 under ASTM G48-00 norm was also studied. The addition of copper favours the nucleation of pits. The addition of tin slightly improves the corrosion resistance. The synergic effect of Cu-Sn was positive at low concentrations. (Author) 10 refs
