Chemical Etching of Stainless Steel
« on: June 13, 2009, 05:28:00 AM »
Hello,

Does anyone here know the procedure for etching stainless steel? I've tried googling
it but I cannot find it. I hope you can help me out.

Thanks.

I guess that there are many types of stainless steel and each one may require different procedure.

I am by no means an expert in this subject, but a strong acid should do it.
Or are you talking about photo-etching, i.e. using a photoresist chemical?

But for just regular etching, oncentrated hydrofluoric acid would do it. I would look up what chemicals are used to etch semiconductors. They are more resistant than metals, so that should give you a ceiling to work under.

Just a strong suggestion,

Be VERY careful when working around Hydrofluoric acid - it is quite toxic to you and your bones..

Sincerely,
