Hydrogen embrittlement relief

What is Hydrogen Embrittlement Relief/Baking?

Hydrogen embrittlement, or baking, is an embrittlement of a metal or alloy caused by absorption of hydrogen during a pickling, cleaning, or plating process.


  • Parts can either be batched or suspended on a rack
  • No dimensional change
  • Does not affect conductivity or corrosion resistance
  • Stress relief process
  • Parts that are undergoing electrochemical surface treatments, such as pickling and electroplating at high current are more susceptible to hydrogen embrittlement
  • Simple hydrogen bake-out cycle can be performed to reduce the risk the of hydrogen damage
