Summary for hard chrome plating nitrided steels Discussion
Hard chrome plating of nitrided steels is the central question here: the poster asks what pretreatment, such as etching, cleaning, or any special steps, should be used before hard chromium plating nitrided steels. The excerpt does not include any technical replies or differing opinions, only a reference to Robert K. Guffie’s book "Hard Chromium Plating" as a possible source of guidance. Because no answer text is shown, the thread itself does not provide a confirmed process recommendation, but it clearly frames the need for careful pretreatment knowledge before attempting chrome on nitrided parts.

Q. Can somebody advice me about pre treatment techniques like etching, cleaning etc. or any special treatment for nitrided steels before hard chrome plating.
