hydrogen embrittlement

Hydrogen embrittlement is a commonly occurred problem that has been experienced for several years. Recently even new and unexpected type of hydrogen embrittlement problem is seen in aerospace industry. This type of corrosion occurs when an essentially hydrogen free material is mechanically evaluated in gaseous hydrogen. It is well agreed among investigators that molecular hydrogen … Continue reading Occurrence of Hydrogen Embrittlement and how to prevent it

Inconel 718 is sensitive to stress corrosion cracking in hot waters, in caustic solutions and in hot chloride solutions, comprising of hydrogen sulfide or acids. Many stress corrosion cracking studies performed for the aerospace plants are not relevant to the oil and gas plant applications of the specificity of conditions needed for stress corrosion cracking. … Continue reading Evaluation of Stress Corrosion cracking of Inconel 718 in oil and gas field
