Microstructure Optimization to Prevent Hydrogen-Induced Cracking of API X70 Pipeline Steels in Sour Environments
… charging experiment was used to introduce HIC in API 5L X70 pipeline steels with four different thermo-mechanical control processing (TMCP) parameters. Using the scanning electron microscope (SEM), HIC cracks at the cross-section of samples were observed. The SEM observations indicate that the …

Influence of crystallographic texture in X70 pipeline steels on toughness anisotropy and delamination
… texture in four commercially-produced API X70 pipeline steels and their relation to planar anisotropy of toughness and delamination were evaluated. The experimental steels were processed through either a hot strip mill, a Steckel mill, or a compact strip mill. Different processing …
