Silicon Steel

Silicon (Si) steels are alloys of Fe and Si having important electrical applications (motors, transformers, etc.). With low-C steels, nonoriented (NO) steels and grain-oriented (GO) Si steels are referred to as electrical steels.NO Si steels have applications in rotating machinery; GO Si steels are used in devices (e.g., transformers) where an EMD parallel to a roll direction is desired.
