High hardness steels are highly susceptible to hydrogen embrittlement. One mitigation strategy includes the introduction of strong hydrogen traps to arrest diffusible hydrogen. An investigation was made into implementation of strong hydrogen traps via alloying and process modification to produce a high hardness steel with a reduced sensitivity to hydrogen embrittlement. The material was directly compared to a baseline alloy free of traps. Both materials were evaluated in terms of hardness, energy absorption, and hydrogen sensitivity. Subsize tensile samples were electrochemically charged with hydrogen and slow strain rate testing was performed. The comparison of the modified alloy to the baseline demonstrated the effect of microalloying and tempering times on reducing the sensitivity of the material to hydrogen embrittlement.
