What Is Non Grain Oriented Semi Processed Steel?

Non Grain Oriented (NGO) semi‑processed steel refers to electrical steels that deliver consistent magnetic properties regardless of direction. These materials are integral to the cores of rotating machines, power generators, electric motors, and small transformers. The “semi‑processed” designation indicates that the steel undergoes additional annealing after the initial punching to fine‑tune its magnetic characteristics.
