Article Preview

Azovstal Iron & Steel Works (Ukraine) together with I.P. Bardin Central Research Institute (Russia) carry out research intended for development and realization of new HSLA-steels for large diameter gas pipelines of strength categories X60 through X80. A concept that has been recently adopted for creation of new pipeline steels calls for lower carbon content, bigger role of Nb microalloying, economical alloying with elements improving austenite resistance to perlite transformation, thermomechanical controlled rolling with strain finishing in two-phase γ+α-region. This paper describes the research results obtained for commercial lots of rolled steel plates of various alloying systems intended for X65 and X80 longitudinally electric welded pipes.
