  • Method for producing a non-grain-oriented higher-strength electrical strip and use thereof
    Patent number: 9627116
    Abstract: A method for producing a higher-strength, non-grain-oriented electrical strip, according to which a slab is cast from a molten mass, the slab is hot-rolled and then cold-rolled—optionally a hot-strip annealing can be carried out between the hot-rolling and the cold-rolling—and the cold strip is annealed in order to produce a partially recrystallized structure so that the mechanical strength values ReH can be set within the range of 450 MPa to 850 MPa at an annealing temperature of between 600° C. and 800° C. for 60 s to 300 s.

  • NON-GRAIN-ORIENTED HIGHER-STRENGTH ELECTRICAL STRIP WITH HIGH POLARISATION AND METHOD FOR THE PRODUCTION THEREOF
    Publication number: 20140373340
    Abstract: A higher-strength, non-grain-oriented electrical strip with high polarization, the electrical strip consisting of a steel alloy, wherein the limits of the following elements are maintained: Mn between 0.35 mass % and 0.65 mass %, Si between 2.0 mass % and 3.0 mass %, Al between 0.8 mass % and 1.4 mass %, and P between 0.14 mass % and 0.24 mass %; and a method for the production thereof.
