Abstract:

The structure-corrosion properties interrelation for the Fe-Cr-Ni maraging steels alloyed by Mo, Ti and Cu has been studied to obtain corrosion evidence for 30, 75 and 90 % H2SO4 solutions. In general, an increase in sulfuric acid concentrations promotes passivation due to higher oxidation. However ageing conditions is a very significant concern. Ageing at 450° followed by separation of a solid solution about Cr is most hazardous in a weak oxidizing medium since the steel tends to pitting after holding for 6 hours. Ageing at the intergranular temperature range is not suitable for oxidizing media, probably due to the formation of two solid solutions, α and γ, and to different solubility of alloying elements, Mo, for example.
