—Results of predicting the long-term corrosion losses of structural metals in the continental territory of Russia with a rural atmosphere and in some locations with an urban atmosphere are given. To predict the long-term corrosion losses, a power and linear law is adopted. Two options for estimating the coefficients that control the power and linear stages of the law are used. The first option is described in international standard ISO 9224 (ISO version). The second option (new version) uses new dose–response functions to predict the corrosion losses of metals in the first year, stabilization time τ stab equal to 6 years, and the stochastic relationship established between coefficient n that characterizes the protective properties of corrosion products and the aggressiveness of the atmosphere. According to the results obtained in predicting the long-term corrosion losses for the two options, the mappings of the territory of Russia for 10 and 20 years are given. The mapping versions are comparatively analyzed.
