...The effect of absorbed hydrogen on toughness and fatigue properties of two pipeline steels at low temperature were studied in the previous articles ^{12 , 13} . To carry out these tests an electrochemical method to charge large steel specimens with hydrogen was set up before mechanical...

... carbon manganese steels pipeline steels strain sulfides sour gas cracking hardness welded joints MAG welding INTRODUCTION The specific problems associated with the use of steels in H₂S containing environments have been extensively documented. One of these is known as sulfide stress...

...Abstract The electrochemical and stress corrosion cracking behavior of two pipeline steels commonly used in China were studied in a range of carbonate/bicarbonate solutions using potentiodynamic polarization techniques and the SCC tests. The influences of concentrations of carbonate, bicarbonate...

...Stress corrosion cracking (SCC) was first observed on natural gas pipelines in the early 1960s and since then has been found on pipelines in many countries [ 1 ]. Pipeline steels are known to be susceptible to two forms of stress-corrosion cracking (SCC), commonly known as high-pH (or classical...

.... The results show that carbon steels in NaCl solutions have less pitting sensitivity than stainless steel, although they have a much higher general corrosion rate than stainless steel. On the other hand, one of pipeline steels, API 5L grade X70 has a higher sensitivity for suffering from pitting corrosion than...

...Abstract Microalloyed pipeline steels have been developed for applications in hydrogen sulfide environments (sour environments), focusing on the required yield strength. Nevertheless, the cracking susceptibility is mainly affected by the microstructure produced during the manufacturing processes...

... into definite cracks (defined as ≥100 μm in length) is being studied. Although not specifically studied in the program, residual stress is also known to affect crack initiation and early-stage growth. stress corrosion cracking near-neutral pH SCC pipeline steels probabilistic model initiation INTRODUCTION...

... was used in order to measure the applied stress intensity, K_I ¹¹ . Abstract The susceptibility of microalloyed pipeline steels to stress corrosion cracking is strongly affected by the microstructure. Discontinuities like non-metallic inclusions, grain boundary segregates...
