Silicon Steel

Silicon Steel Division

In alternating current equipment and machines, in such places as transformers cores or as magnetic core materials in motors, the use of plain carbon steel may cause the electrical losses to be unduly high.

The 1 to 4 per cent silicon steels when used as a replacement for the plain carbon steels, serves to lessen materially the electrical losses, they posses increased electrical resistance, they show relatively little of an aging effect, and they are at the same time inexpensive alloy steels.

The silicon steel first patented by Sir Robert Hadfield in about 1900, has made possible the development of more efficient and more powerful electrical apparatus.

There are two main groups of Silicon Steel: Grain Oriented and Non Grain Oriented

Grain Oriented

silicios5

Non Grain Oriented

silicios4

Grain Oriented

Mainly used in power transformers, distribution transformers, testing transformers, rural one phase transformers, etc.
