Electrical steel made without special processing to control crystal orientation, non-oriented steel, usually has a silicon level of 2 to 3.5% and has similar magnetic properties in all directions, i.e., it is isotropic. Cold-rolled non-grain-oriented steel is often abbreviated to CRNGO.

Production facilities have an annual capacity to produce about 200,000 tonnes of electrical steel. In 2006, the company produced 180,000 tonnes of grain-oriented steel and 16,000 tonnes of non-grain-oriented steel. Novolipetsk Steel (NLMK) is the major supplier of hot-rolled coils for further cold rolling at VIZ-Stal. The main customers of ...
The mechanism of secondary recrystallization is a small and uniform primary grain size, achieved through the inhibition of normal grain growth by fine precipitates called inhibitors. [2] Goss grains are named in honor of Norman P. Goss, the inventor of grain-oriented electrical steel circa 1934.
If all conditions are as defined in the standard, the standard deviation of the reproducibility of the values is not greater than 1.5% up to 1.5 T [clarification needed] for non-oriented electrical steel and up to 1.7 T for grain-oriented electrical steel.
