Removing of hard chrome coating

Hi,

I want to remove the hard chrome coating deposited on the steel 4130. Any suggestion will be much appreciated. Thanks a lot.

Dear Mr Mahdey,

You can remove chromium from steel anodic in a solution of about 150-250 g/l sodium hydroxide. The voltage is about 2-6 V.

Kind regards,
