Hi All, Does anyone know of a wet chemical etch for 316L stainless steel? We're trying to uniformly etch away, or at least thin, 100um of stainless steel from a magnesium diboride core. It would be nice if the magnesium diboride core was not etched, or at least etched at a much slower rate than the stainless steel. Thanks in advance, Novak Farrington Microelectronics and Nanostructures Group School of Electrical and Electronic Engineering Sackville Street Building The University of Manchester Manchester M60 1QD
