Corrosion Performance and Tribological Properties of Carbonitrided 304 Stainless Steel

In general, the solid solution austenitic phase (γ) with high chromium content (12 % 20 %) is responsible about the excellent corrosion performance of austenitic alloys. This advantage allows these alloys to use in biomedical, food and chemical, pulp and paper chemical, petrochemical, heat exchange and nuclear power plant industries [1-4]. However, most of these applications are suffering from their relatively low hardness and poor tribological properties.
