1. PN-Core
 |
The non-oriented electrical steel features
even magnetic properties in the rolling direction and
in other directions. They are widely used for iron core
materials of rotating machines ranging from large-size
power generators to small-size precision electric motors.
They are also desirable for iron core of small-size power
transformers. |
2. PNM-Core
|
It is utilized as steel material for magnetic
switches and improved in wear resistance and residual
magnetism. |
