ABSTRACT:
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 construction where the estimated tensile stress component in any direction perpendicular 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.
