electropolishing 440C stainless steel

[kenvlach]

I would appreciate any information on the solutions and procedures for electropolishing 440C stainless. Owing to its high carbon content, the customary phosphoric-sulfuric acid solutions do not work for this alloy. The usual guidebooks (Metal Finishing, Products Finishing, ASM Handbooks, etc.) do not give specific info.<br><A HREF="mailto:kenvlach@aol.com">kenvlach@aol.com</A>

Hello kenvlach:<br>How are you? About 12-13 years ago, I used a chemical polishing solution to remove burrs from thin, stainless steel parts. I don't know the type of stainless I was working with. The chemical was called Diversy (Diversey) and, unfortunately, I don't know if it is still available.<br><br>Have a great weekend,<br>steved

 

i went some info about electropolishing for stainless steel(300--400series)

 

There is a company near Jacksonville, Florida that electropolishes all types of stainless steel for medical and other uses.The name of the company escapes me at this time, but they use a metal passivization process for metal removel. You can specifiy a particular amount of metal removal or a degree of polish and luster. I used them for polishing a 13.8MO Stainless, which is a medium carbon content , medium nickle alloy.

I believe that I remember the name: GEM Electopolishing.

 

hello,
chemical engineers. i am looking for formula for electropolishing of stainless steel 420 series.If any body knows the chemical compositions and handeling of whole above proccess.
