The paper deals with the study of the behaviour to hydrogen embrittlement of micro-alloyed steels for buried pipeline and sealine under cathodic protection. Steels with different chemical composition and microstructure and yield strength ranging between 60 to 110 ksi (420 to 770 MPa) were considered in order to compare new steels with traditional grades. The susceptibility to hydrogen embrittlement was assessed through slow strain rate tests performed in a sodium chloride solution at cathodic potentials between -2 to -0.8 V vs SCE reference electrode in the ranges 10 -7 to 10 -3 s -1 strain rates. The susceptibility of the steels has been expressed in terms of critical value of potential for hydrogen embrittlement as a function of strain rate.

Abstract
The paper deals with the study of the behaviour to hydrogen embrittlement of micro-alloyed steels for buried pipeline and sealine under cathodic protection. Steels with different chemical composition and microstructure and yield strength ranging between 60 to 110 ksi (420 to 770 MPa) were considered in order to compare new steels with traditional grades. The susceptibility to hydrogen embrittlement was assessed through slow strain rate tests performed in a sodium chloride solution at cathodic potentials between -2 to -0.8 V vs SCE reference electrode in the ranges 10 -7 to 10 -3 s -1 strain rates. The susceptibility of the steels has been expressed in terms of critical value of potential for hydrogen embrittlement as a function of strain rate.Pubblicazioni consigliate
