Effect of operating degradation in Arctic conditions on physical and mechanical properties of 09Mn2Si pipeline steel
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...
