Abstract

The principal objective of this project was to assess the HIC resistance of a range of controlled rolled ultralow carbon enhanced alloy content AF/bainitic steels, compared with traditional ferrite-pearlite materials. The various stages of the project are described, including the development of a suitable laboratory slab casting technique giving reproducible centreline segregation, the processing of a number of alloys to strength levels within the range X65-X80, HIC assessment and hydrogen permeation studies, and examination of segregation profiles in relation to compositional variables and HIC development. Finally, the results of a limited HIC assessment of laboratory simulated linepipe seam welds on the ultralow carbon AF/bainite and ferrite-pearlite steels is described.
