Silicon steel, also known as electrical steel, is a specialized ferritic alloy of iron and silicon, widely used for its magnetic properties in motors and transformers. Containing 0.5%-4.5% silicon by weight and less than 0.08% carbon, silicon steel enhances magnetic softness and electrical resistivity. Available in two forms—grain-oriented (GO) and non-oriented (NGO)—it is essential in the efficient generation, distribution, and consumption of electricity. Applications include motors, transformers, wind turbines, and electrical appliances.

High permeability, low coercivity, and high resistivity minimize hysteresis and eddy current losses.
Requires high plasticity, smooth surface, and minimal harmful inclusions for efficient punching and shearing.
HXH supplies cold-rolled silicon steel with iron loss performance exceeding international standards, replacing outdated hot-rolled processes in China.
