Popis: The mechanical properties, microstructure, fractures, and texture of a trial industrial batch of 07Г2MФБ steel sheet (thickness 21.7 mm) for the manufacture of spiral-seam gas-line pipe (diameter 1420 mm) of strength class X70 at OAO Volzhskii Trubnyi Zavod (VTZ) are investigated. It is shown that the selected chemical composition of the steel and thermomechanical rolling technology yield mechanical properties of the sheet and the basic pipe metal complying with VTZ specifications.
