Paper presented at the CORROSION 2021, April 19–30, 2021
Paper Number: NACE-2021-16798
... Abstract This paper elaborates on a method previously reported that characterized a materials susceptibility to hydrogen embrittlement in a seawater environment under CP by monitoring the crack growth rate of ASTM (1) E1820 1 pre-cracked CT specimens at various constant stress intensity (K...

... on the reproducibility of tests carried out in weld joints due to different fracture susceptibility and film formation ability of the weld joint regions. It was observed that the loss of ductility and the iron sulphide film morphology, and the promoted barrier effect against hydrogen, are dependent on the weld joint...

... behavior suggests that the 725 exhibited the highest susceptibility, while 955 and 945X appeared to exhibit similar fatigue crack growth rate behavior. A static crack growth rate of 10 -6 mm/s (under constant K conditions) was obtained at 50ksivin (55MPavm) on 725, while it required K values of about...

... in environments that contain H 2 S, particularly in relation to the susceptibility to sulfide stress corrosion cracking (SSC) assisted by H 2 S. The objective of the study is to evaluate the effects of temperature, H 2 S, and Cl - concentration on the pitting onset of pitting and the likelihood of SSC. Using...

However, there is still no clear image to describe how the impurities affect corrosion due to very limited database and some controversial results. More importantly, there is a serious concern on the stress corrosion cracking (SCC) susceptibility...
