Specify Grade
Non
oriented silicon steels with 1.8 to 3.0% Si.
The fully processed grades have
higher Si content and are harder, Rb>75, after the final anneal.
They are available varnish coated. The semi- processed grades have a
phosphate insulation, are always annealed after stamping, yielding
high permeability, and lower core loss for given silicon content.
