The anisotropy of mechanical properties in the context of steels used to fabricate large diameter pipes can be detrimental to the design and performance of the pipes. We examine here the anisotropy of strength and toughness, and with the help of detailed characterisation show that there is a complex interaction between the ability of the steel to delaminate on the rolling plane and the crystallographic texture, which promotes brittle fracture on the macroscopic fracture plane of Charpy specimens.
