Under hydrogen contained service environment, hydrogen atoms can permeation into internal of the metal material. This will cause hydrogen embrittlement or other damage, leading to sudden cracking and has serious threat to engineering structure safety. The hydrogen embrittlement sensitivity analysis technique focuses on the combination of service condition simulation and material degradation caused by hydrogen. The main analysis methods include hydrogen content test, hydrogen permeation test, slow strain rate tensile test (SSRT), fracture toughness test, fatigue test, and hydrogen induced cracking test, etc. Through HE risk evaluation, the service safety boundary can be built for different material under various environments.
