ABSTRACT OF THE DISCLOSURE The invention refers to constructions of rolled steel materials and to a process for the preparation of such constructions. The invention resides in the improvement of using in the parts of said construc- tion where the estimated tensile stress component in any direction perpendi- cular to the rolling direction of the material is equal to or greater than the estimated tensile stress component in the rolling direction of the material, a steel containing about 0.002 - 0.05 % by weight of sulphur and tellurium in an amount of about 0.002 - 0.009 % by weight + about 0.1 times the sulphur content in % by weight, the content of silicate-bound oxygen being less than about 300 parts per million.
