The paper presents the results of the study how the sub-zero treatment of Vanadis 6 steel influences the corrosion resistance of the material. The sub-zero treatment was performed at -196 oC in liquid nitrogen for 17 h. The results obtained by sub-zero treatment were compared with those achieved by conventional heat treatment. The main object of the analysis was the effect of these treatments on the corrosion resistance of the steel tested. Corrosion resistance tests revealed slight improvement in corrosion resistance by the application of sub-zero treatment. Tempering treatment, on the other hand, induced a worsening of corrosion behaviour of the material.Keywords: Sub-zero treatment, liquid nitrogen, Vanadis 6 steel, corrosion resistance
