Relationships between the effective chromium and carbon contents and the parameter of resistance ( k ) are discussed in this paper in relation to their applicability to stabilized steels. The efficiency coefficients of stabilization in Ti‐stabilized steels of four types, determined according to the completeness of chemical composition, were the basis for indicating the parameters of the resistance of these steels to intergranular corrosion. The comparison with low carbon steels, two of optimized chemical composition, one stabilized with niobium, reveals sufficient resistance to, and guarantee of this resistance to the intergranular corrosion for the 08Cr18Ni10Ti grade. The method of evaluating the resistance to intergranular attack based on calculating the minimum effective chromium content, the maximum effective carbon content and the resistance parameter k that issues therefrom, is suitable for practical application directly during the making of stainless steels.
