Fine resolution etching of stainless steel

I am trying to chemically etch fine features (60um line widths with 40um spacings) into a 25um thick piece of 302 stainless steel film that is mounted on a PTFE substrate for an electronics application. I am having a tough time getting the required resolution in Stainless Steel that I could get in Copper sheet. I am using ferric chloride ⇦ on eBay or Amazon [affil links] as my etchant.

Is this a fundamental problem of the alloy vs. a single element metal, or should there be a way to accomplish what I am trying to do?

What would be the optimal grade of SS to use for fine resolution chemical etching?
