Cold rolled non grain oriented steel is often abbreviated to CRNGO. It usually has a silicon level of 2 to 3.5% and has similar magnetic properties in all directions, i.e., it is isotropic. Mainly used in rotating equipment, for example, electric motors, generators and over frequency and high-frequency converters. https://www.cnsteelsale.com/crngo-cold-rolled-non-oriented-electrical-steel-coil_p60.html
