Question
By adding silicon to steel, which of the following property is enhanced?
- Resistance to corrosion
- Electrical characteristics
- Magnetic property
- Ductility
Hint:
- Silicon helps to purify the iron ore during the smelting process by deoxidizing it and removing other impurities from it.
The correct answer is: Electrical characteristics
- Silicon steels are ferritic alloys of iron and silicon that have magnetic properties which make them useful in motors and transformers
- Silicon helps to purify the iron ore during the smelting process by deoxidizing it and removing other impurities from it.
- The silicon additions improve magnetic softness and increase the electrical resistivity.
