Silicon steel and its application

Silicon steel

Silicon addition improves the
electrical properties of steel. It also increases fatigue strength and
ductility.

Applications of Silicon steel

1. Steel
with

    Mn  = 1 %,       Si = 2%     and      C = 0.4 to 0.6%

    has very high elastic limit and is used for springs.

2. Steel
containing 5 to 7% silicon retains its hardness and resistance to oxidation at high
temperature. It is used for making internal combustion engines.

3. Steel possessing 13% Si has a very
high corrosion resistance and it can be used in chemical industrial
applications.

4. Steel
possessing 1% Si and up to 0.95% Mn is suitable for structural purposes.
