The influence of cutting technique on the magnetic properties of electrical steels

Magnetic permeability and losses at 1.5 T of a 2% Si non-oriented fully processed electrical steel Epstein strip, cut by different techniques (punching, guillotine, laser and photocorrosion), have lower values at the as-cut condition, when compared to after annealing. Permeability at 1.5 T showed to...

Summary:Magnetic permeability and losses at 1.5 T of a 2% Si non-oriented fully processed electrical steel Epstein strip, cut by different techniques (punching, guillotine, laser and photocorrosion), have lower values at the as-cut condition, when compared to after annealing. Permeability at 1.5 T showed to be more affected by cutting than the losses. Photocorrosion is slightly less harmful, but annealing did not improve it as much as it did to samples cut with guillotine.
