Hi!
I am wondering if someone has some information about stainless steel
etchants, or vendors. We are going to etch 200 um thick stainless steel.
The stainless steel has some of Cr and Ni. We tried some etchants
followed by a Metal Handbook. But the etch rate is not fast enough.
I heard ferric chloride can etch the stainless steel. But I don't have
the information about the concentration. If you give us some information,
We will really appreciate that.
