Abstract

Structural steels used in the production of welded metal structures in contemporary domestic and overseas practice are analyzed. Common tendencies and differences from strength classes used most frequently are revealed in steel alloy systems used in the production of thick rolled sheet. Simulation of normalizing and thermomechanical rolling, and also normalizing for steel of the alloy system C–Mn–Si–Nb, is performed under laboratory conditions. The possibility is demonstrated of preparing rolled product of strength class 390 with an increased level of brittle failure resistance from economically alloyed steel using thermomechanical (normalizing) rolling technology.

Domestic steels of strength classes 345 and 390 are based on the C–Mn–Si composition with additional economical alloying with chromium, nickel, and microalloying with niobium, controlled by technical specifications TU 14-1-5120-2008 (steels 15KhSNDA and 10KhSNDA), and they are used widely in bridge building.
