  abstract  = {Quenching and partitioning ( {Q\&P}) treatments result in promising mechanical properties of advanced highstrength
steels. However, recent studies indicate that  {Q\&P} steels are very susceptible to hydrogen embrittlement
(HE). Using slow strain-rate tests, the effects of hydrogen charging in different media without and with recombination
poison were investigated for Fe-0.38C-1.92Si-0.66Mn-1.39Cr in quenched and tempered as well as
 {Q\&P} conditions. In addition, corrosion tests and Zn electroplating of tensile specimens were performed. In both
heat-treatment states, it was found that the intensified hydrogen-charging conditions using a recombination
poison strongly impact the result of HE investigations: HE only occurs when a recombination poison is present.
In addition, the negative influence of hydrogen formed during Zn electroplating can be limited by using proper
electrolytes and electrical parameters. This allows keeping the HE susceptibility of the  {Q\&P} steel low in practical
applications when recombination poisons are absent.},
