Abstract
Quantitative estimation of structural banding in alloy steels 40KhN2MA, 38KhGMA, and 20KhN3A is performed. The dependence of anisotropy index according to GOST R 54570 (ASTM E 1268) on the steel bar diameter and sample selection position is determined. It is shown that there is a direct relationship between structural banding, specified by the anisotropy index and steel mechanical properties (scatter of the microhardness values and anisotropy of the impact strength).
