ASTM F519 - 18

Hydrogen embrittlement occurs when metals are subjected to hydrogen uptake during plating processes or as a result of corrosion in the service environment. This causes the metal to lose ductility and toughness and become brittle, resulting in premature failure under static loads. There are two types of Hydrogen Embrittlement HE : Internal HE, which occurs when the hydrogen enters metal during forming, coating, plating, cleaning, and finishing operations; and Environmental HE, resulting from hydrogen being absorbed from the environment. Element performs HE testing for coating and plating processes that can cause hydrogen embrittlement in steels, and on the metals in simulated service environments.
