Directions of Improving Gas and Oil Pipeline Structural Materials

Achievements are considered for contemporary metallurgy and metal science in improving quality and operating properties, and also trends in the development of low alloy steels for oil and gas pipelines. The possibility is analyzed for using ultralow-alloy austenitic martensitic steels as promising structural materials for seamless pipes and connections for main pipelines. The most essential parameters for composition and technology affecting a set of steel mechanical properties with a low-carbon microstructure are revealed.
