Does Zinc Plating on 17 HRC steel need hydrogen embrittlement relief?
October 22, 2008
I am using SAE 1020 with hardness 17 HRC. I am doing Zinc Plating with Green Passivation. Does it need a Hydrogen Dembrittlement process. If so, please advise the process

For 1020 at that hardness you most likely do not need to do a de-embrittlement bake. The normal requirement starts around 36. BUT, any buyer can demand it (and be charged appropriately for it). Typical cycle would be a bake at 360 to 400F for 1 to 3 hours.
