What is Hydrogen Embrittlement? - Causes, Effects and hydrogen embrittlement susceptibility of x70 pipeline

Hydrogen Embrittlement occurs when metals become brittle as a result of the introduction and diffusion of hydrogen into the material. The degree of embrittlement is influenced both by the amount of hydrogen absorbed and the microstructure of the material. Microstructures which bestow high strength, often monitored by hardness level, or having specific distributions of grain boundary particles or inclusions, can result in increased susceptibility to embrittlement.Weld Hydrogen Cracking Susceptibility | International hydrogen embrittlement susceptibility of x70 pipelineJan 15, 2021 · Cracking susceptibility is described through the definition of material ductility and embrittlement indices, which are derived from the hydrogen susceptibility curves.
