Grain-oriented steel is a type of electrical steel that is specifically designed to improve the efficiency of electrical devices. It has a unique microstructure that aligns the grains of iron, allowing for better magnetic properties. This alignment reduces energy losses when the steel is used in transformers and other electrical equipment. The manufacturing process of grain-oriented steel involves careful control of temperature and processing techniques. This results in a material that exhibits high permeability and low core loss, making it ideal for use in transformers, motors, and other applications where efficient magnetic performance is crucial.
