Abstract

A criterion is suggested for evaluating steel tendency to forming chemical inhomogeneity based on calculating distribution coefficients and accommodation of elements in steel composition. It is shown that the criterion proposed correlates with carbon liquation coefficients through the cross section of forging ingots of different weight (0.5–650 tons): with an increase in the value of the suggested criterion there is an increase in carbon liquation, and consequently chemical composition inhomogeneity. The use of this criterion in developing steel composition for new grades will make it possible to reduce their inclination for forming chemical inhomogeneity providing greater metal product property stability.
