The article develops one-dimensional linear regression mathematical models that establish the relationship between the activation potentials Ecrev, repassivation Erep, and corrosion Ecor of the 06KhN28MDT alloy used in the production of plate-like heat exchangers and its chemical composition and structure components in model recycled water. It has been found that the limiting potential Elim of the alloy shifted in the positive direction with an increase in the content of Cr, Mo, Si, S, the volume of titanium sulph...

A mathematical model was developed, which is based on a multivariate regression dependence and establishes the relationship between the critical pitting temperature (CPT) of the 06KhN28MDT alloy (similar to AISI 904L steel) and its chemical composition and structural components in model circulating waters with pH 4...8 and chloride concentration from 350 up to 600 mg/liter, which correspond to industrial circulating water during the operation of heat exchangers. Based on the results of the analysis of the develope...
