Microalloying Elements

A steel pipeline containing niobium, vanadium and titanium as microalloying elements was tested for hydrogen embrittlement. Hydrogenated specimens intercritically annealed at relatively low temperature to develop martensite islands in a ferrite matrix basically exhibited quasi-cleavage fracture with some ductile dimpling. The objective of this investigation, carried out by the principal investigator is to study the mechanical properties and susceptibility to hydrogen embrittlement effects on steel pipeline used for natural gas transport.

Hydrogen Induced Cracking

The hydrogen-induced cracking of X70 pipeline steel was investigated in low-temperature and low-dissolved-oxygen seawater by means of potentiodynamic polarization, slow strain rate tests (SSRT), and hydrogen permeation measurements. The results showed that the hydrogen evolution potential of X70 steel in low-temperature and low-dissolved-oxygen seawater decreased compared with the normal-temperature seawater. The susceptibility to hydrogen embrittlement increased as the potential shifted in the negative direction. When the polarization potentials were below −1,050 mV vs. saturated calomel electrode (SCE) in low-temperature and low-dissolved-oxygen seawater, the fracture surfaces exhibited quasi-cleavage fracture.
