the effect of metallurgical parameters influencing the susceptibility of the steel grades, used for gas and oil pipe, to hydrogen induced cracking and sulfide stress corrosion cracking has been studied. the study of the recent investigations suggests that the shape and the nature of inclusions, microstructures, sulfur content and desulfurization as well as the nature of alloying elements in ste...

The mechanical performance of API 5L grade B steel, after undergoing a thermochemical boriding process, was assessed. We quantified the boride layer microhardness over cross-section specimens, with aim characterizing resistance under different conditions. pipeline steel analyzed because changes in yield strength, ultimate tensile and ductility treatment boron. These oil gas pipelines must work ...
