(OP)
I have to mark our 316 SS mat'l Fitting product.  The marking process will be done using electrical engraved.

Is there anyone has the same problem with me before or heard about it...please advise me.

Hi Yose,
If you still have a need, we can mark your SS parts with a permanent black mark. You can see examples at:www.custom-etched.com.

RE: Corrosion at 316SS caused by engraving process of marking

disturbing the surface will decrease corrosion resistance if oxide is formed or if inclusions are exposed. corrosion resistance can be restored by pickling with nitric acid.

Careful with the icehorse1 response. Make sure that the marker is suitable for use on stainless and has acceptable chloride and halide contents.

RE: Corrosion at 316SS caused by engraving process of marking

Good point AEF! You can get the particulars, including chemical resistance testing at: www.cerdecmark.com. The laser energy (heat) actual anneals the active pigment in the formula onto the stainless steel, creating a new alloy which is slightly raised on the SS surface.
