This document defines the steel grades of grain-oriented electrical steel strip and sheet in nominal thicknesses of 0,20 mm, 0,23 mm, 0,27 mm, 0,30 mm and 0,35 mm. In particular, it gives general requirements, magnetic properties, geometric characteristics, tolerances and technological characteristics, as well as inspection procedures.
This document applies to Goss textured grain-oriented electrical steel strip and sheet supplied in the final annealed condition in coils or sheets and intended for the construction of magnetic circuits.
The grades are grouped into three classes:
conventional grades;
high permeability grades;
magnetic domain refined high permeability grades.
They correspond to Class C22 of IEC 60404‑1.
