Abstract

The article explores the development of a new steel microstructure for main gas pipeline pipes crossing active tectonic disturbance zones. Traditional steels with ferrite-pearlite or ferrite-bainite structures do not meet the required properties. The new microstructure, consisting of ferrite, martensite, and M/A components, provides enhanced strength, ductility, and cold resistance. Laboratory and industrial experiments demonstrate the superior performance of this microstructure, making it a promising solution for challenging pipeline conditions.
