Web12 Sep 2013 · PM2000 ODS steel showed significantly better corrosion resistance compared to austenitic stainless steels and nickel based alloys tested in the same conditions. The high corrosion resistance is attributed to the formation of a dense and protective aluminum-rich oxide layer on the surface. WebTransmission Electron Microscopy (TEM) with corresponding modern analytical techniques have been used to study morphology, structure and chemical composition of large complex precipitations in Al containing steels (PM 2000).
