Transformer Steel FAQS

Silicon steel, also known as electrical steel or transformer steel, is a specialized alloy primarily composed of iron and silicon. It is designed to exhibit specific magnetic properties suitable for electrical applications.

There are two main types: grain-oriented silicon steel, which is optimized for directional magnetic properties, and non-oriented silicon steel, which has isotropic magnetic properties.

Transformer steel is produced through a process of hot rolling and annealing, followed by cold rolling and final annealing to achieve the desired magnetic properties and grain orientation.

Lamination steel is used in various electrical devices, including transformers, electric motors, generators, and magnetic cores in electrical appliances.
