Investigation of the microstructure and mechanical properties of heavy plates strength grade S355 in thickness range 5–150 mm from low carbon structural steels, microalloyed with vanadium and regulated nitrogen content was made. Main parameters of the microstructure and mechanical properties after hot rolling, normalizing and normalizing rolling were compared. The influence of temperature during heat treatment on the level of mechanical properties was determined in laboratory conditions. The contribution of hardening effect of second phase particles to the strength level of the studied steels was defined. © 2015, Allerton Press, Inc. Source

Lamellar tearing may develop in building metal structures using low-carbon steels in welded joints and assemblies. A reason for its occurrence is an inadequate level of ductility with respect to the degree of welded structure stress in the plate thickness direction. Using results of thick plate tests, we demonstrate the effect of harmful impurities and also of the strength level, structural inhomogeneity, and low-carbon steel slab thickness on the level of relative reduction of area in the thickness direction of plate produced in the NLMK DanSteel 4200 rolling mill. © 2015 Springer Science+Business Media New York.
