Permanent domain refinement of grain oriented electrical steel strip is obtained in a high speed two-stage process. The process removes the glass in narrow regions which just expose the base metal. An electrolytic etch is then used to deepen the regions into the base metal and minimize damage to the remaining glass film. Control of acid concentration and temperature in the electrolytic bath allows a greater increase in productivity. A further feature of the process is the use of permeability measurements to optimize the depth of the etched regions. The improved core loss produced by the process will survive a stress relief anneal.
