Hydrogen Embrittlement

An environmentally assisted failure mechanism caused by the combined action of hydrogen and residual or applied stresses. Hydrogen may be introduced during plating, chroming, or welding. Higher strength steels should be baked to drive off hydrogen immediately after plating or chroming. Low hydrogen electrodes should be used when welding steels susceptible to hydrogen embrittlement.
