This paper presents results of research, which was targeted to define reasons of the short life of sieves made from a 0.8mm diameter wire of the INCONEL 600 alloy. It was noticed that when the sieves were used in the device for the nitrogen acid production there appeared a total loss of plastic properties of the wire. It was caused by the process of diffusion of oxygen, nitrogen and metal ions which was not stopped although the protective layer of the scale was produced. It resulted in the substantial decrease of the chromium contents (to ca 1.5%) and in oxidation of the grain boundary in the wire outer layer. The diffusion of nitrogen to the wire core caused in turn the precipitation of many Cr₂N nitrides in the core.
