The structure and mechanical properties of 09Mn2Si steel of the main pipeline “Kysyl–Syr–Mustakh–Yakutsk” cut out from a linear part fragment of the pipe with the outer diameter of 530 mm and a wall thickness of 7 mm at the region “Berge–Yakutsk” after 37 years of operation were investigated. It was...
