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.

The introduction of “clean steels” was thought to have cured the problem of temper embrittlement in low alloy steels. However, even these steels exhibit temper embrittlement at services temperature above 400°C. Initial studies of temper embrittlement of clean steels used Auger electron spectrometry of fracture surfaces. The failure was found to occur along the prior austenite grain boundaries (PAGBs) where P segregation was found. It has been reported that the concentration of segregants changes along individual PAGB facets, as well as between the facets of different PAGBs. It was proposed that different elements segregate to different PAGBs, depending on their orientation. Differences in segregation along individual PAGBs were attributed to precipitation during thermal exposure, as identified by AEM. The cause of temper embrittlement is still unknown, as there are doubts about the role of precipitation. This implies that each PAGB may have a different chemistry.
