Oxide layer on EDM cut Austenitic SS
Oxide layer on EDM cut Austenitic SS
(OP)
How do you remove that dark oxide layer on SS
Portions of my parts are very narrow with small holes 3mm and I cannot quite get the TIG brush in the area Also ,,,
Tig brush creates heat which can warp slender parts
Can you recommend some powerful pickling ????
Thank You

Do I need to clean them at all ???
Will that oxide layer outgas or contaminate the vacuum in any way ???

In SS this is typically chemically cleaned by pickling. This will lightly etch the entire surface, depending on how you do it.

Work and health took away our hot nitric and hyroflouic bath
And a good vacuum guy said you don't put EDM wire cut surfaces in high vacuum , so that recast has to be removed somehow
Hand work does it at a time cost

You can buy pre-mixed pickle solution.
Tug's suggestion to send them out for a light electropolish is also very good.
