Steel for Pipes of Strength Class K60 (X70) with Ferrite, Martensite and M/A-Component Microstructure for Sections of Main Pipelines Crossing Active Tectonic Disturbance Zones

Formation of the microstructure and properties of pipe steel grade K60 (X70) are studied using physical modeling of thermomechanical processing in a DUO 300 laboratory mill and industrial experiment. Steel microstructure is investigated and temperature ranges for formation of various phases and stru...
