  • Method of continuous annealing low-carbon electrical sheet steel and duplex product produced thereby
    Patent number: 4326899
    Abstract: A process for producing a low-carbon electrical sheet steel having a superior and unique duplex microstructure having a mid-section of fine-grained ferrite with dispersed carbide precipitates and a coarse grained surface of ferrite without significant precipitates. The unique microstructure is effected by a duplex continuous anneal wherein the steel is first decarburized annealed at 1350.degree.-1500.degree. F. for a time sufficient to decarburize only the surface, and thereafter heat treated to austenitize the steel, followed by controlled cooling to effect the above-described microstructure.
