STRUCTURE AND PROPERTIES OF STRIP FOR LARGE-DIAMETER PIPE MADE FROM STEEL IN STRENGTH CATEGORIES Kh80-Kh100

摘要

We studied structure formation in high-strength strip for trunk pipelines made from steel in strength classes Kh80-Kh100. The structural morphology was shown to have an effect on the mechanical properties of the thick rolled sheet. Weldability studies and low-temperature brittle-fracture-resistance studies were performed on the steels developed as part of this study.
