CRNGO

CRNGO

• 
  Electrical steel made without special processing to control orientation, Non-Oriented Steel, usually has a silicon level of 2 and 3.5% and has smaller magnetic properties in all directions I.E., it is isotropic. Colled-Rolled Non-Grain-Oriented Steel is often abbreviated to CRNGO. Cold rolled Non-Oriented Electrical Steel (Non-Oriented Electrical Steel) the term oriented, when used in conjunction with electrical steel, refers to a crystal structure having magnetic properties that are materially better in a given direction.

  Difference between CRGO and CRNGO - CRGO needs precise alignment due to its anisotropy (The properties that are different along different directions are anistropic properties) but CRNGO can respond to flux changes in all directions (I.E., its properties are isotropic)
