ATI's Grain-Oriented Electrical Steels (GOES) are iron-silicon magnetic alloys. These alloys are used to construct the cores of highly-efficient electric transformers due to their unique magnetic properties.
ATI is a leader in producing Grain-Oriented Electrical Steel (GOES) for the electrical power distribution industry. Our GOES is processed under carefully controlled conditions to develop optimum magnetic characteristics. GOES develops low core losses at high inductions when used as core material in transformers. These features allow more compact, more efficient transformer designs that require less material.
Our grain-oriented electrical steel are provided in the fully-processed condition, with exacting process control ensuring optimum magnetic properties of core loss and permeability in the rolling direction. The natural surface of grain-oriented steel is a glass-like film (AISI C-2) that provides electrical insulation between transformer laminations or wound core laps. Other coatings are also available from the mill to enhance surface insulation. Unlike stainless steels, grain-oriented electrical steel products are tested and sold on the basis of their magnetic and electrical properties. Products are offered in full coil and slit widths specific to product grade.
