Abstract
The corrosion behaviour of some high allied stainless steels, nickel a lloys, titanium and alloy with high Mo content, in industrial acid sol utions with sulphuric acid and ZnSO4, CuSO4, FeSO4, at different tempe ratures from 50 degrees C to 120 degrees C, is presented. The corrosio n rate, the attack kind of the surface and the structural corrosion we re established. Both the stainless steels and Ti-32Mo alloy undergo th e structural corrosionlike cracks and microcracks; the titanium and ni ckel alleys have a very good corrosion resistance in the examined solu tions.
