High corrosion resistance is achieved in the 300 series SS, but due to the low carbon content they do not have the carbides present in wear‐resistant steels. This paper shows results from a combined plasma nitriding surface treatment performed in AISI SS304, that led to the enhancement of 50% in microhardness and the achievement of improved tribological properties of the samples, while keeping its high corrosion resistance. A complete characterization set including results from AES, Vickers hardness, XRD, friction coefficient, and wear rate will be shown for the samples treated by this hybrid nitriding process, in comparison with the conventional ion nitriding method.
