Structural sheet steels 08GNB, 06GNB (F40W), and 09KhMN2D and steel 09G2B imported from Germany are studied. The effect of the layered-banded structure on the anisotropy of the resistance of the steels to brittle fracture is determined using the results of tests of impact specimens cut in different directions with respect to that of rolling. The critical brittle point (CBT) is evaluated in terms of criterion KCV ≥ 0.29 MJ/m2. Metallographic studies and tensile tests aimed at determining the characteristics of short-term strength and ductility are performed.
