ABSTRACT OF THE DISCLOSURE A method is provided for domain refinement of final texture annealed grain-oriented silicon steel by removing portions of the base coating to substantially expose a line pattern of the underlying silicon steel by applying in the pattern an agent to the coated steel, heating the agent to activate it to cause substantial removal of the base coating in the line pattern and effecting heat resistant domain refinement and reduced core loss by allowing thermal and chemical treatment activity on the exposed steel.
