Cold-rolled non-grain-oriented steel is often abbreviated to CRNGO. Grain-oriented electrical steel usually has a silicon level of 3% (Si:11Fe). It is processed in such a way that the optimal properties are developed in the rolling direction, due to a tight control (proposed by Norman P. Goss ) of the crystal orientation relative to the sheet.
