0.30mm Grain-Oriented Silicon Steel for Power Transformers
Grain-oriented silicon electrical steel sheet, 0.30 mm thick and 700 mm wide, with a domain-refined structure that minimizes core loss in power transformers. The material is flat-rolled alloy steel exceeding 600 mm in width, and its grain orientation aligns with the magnetic flux path, a defining characteristic of this tariff item.
Conventional Grain-Oriented Steel CRGO 0.35mm
Conventional grain-oriented (CRGO) silicon electrical steel, 0.35 mm thick and 750 mm wide, standard grade for distribution transformer cores. Its flat-rolled form, width over 600 mm, and grain-oriented crystal structure place it squarely under this tariff item.
Domain-Refined GO Silicon Steel 0.27mm
Domain-refined grain-oriented (GO) silicon electrical steel, 0.27 mm thick and 1100 mm wide, engineered for low losses in high-frequency transformer applications. The wide flat-rolled format and precise grain orientation meet the criteria of this tariff item.
Goss Grain-Oriented Silicon Steel 0.25mm
Goss-textured grain-oriented silicon electrical steel, 0.25 mm thick and 820 mm wide, a classic grade for transformer core laminations. The Goss texture ensures optimal magnetic properties, and the flat-rolled form over 600 mm wide qualifies under this tariff item.
HI-B Grain-Oriented Electrical Steel Plate
High-induction HI-B grade grain-oriented silicon steel plate, 900 mm wide and 0.23 mm thick, designed for high-efficiency transformer laminations. Its flat-rolled form, width over 600 mm, and grain-oriented structure align with this tariff item.
High-Tension Transformer GO Steel Sheet
Grain-oriented silicon steel sheet for high-tension transformers, 0.23 mm thick and 950 mm wide, with a low core loss grade. The wide flat-rolled format and optimized crystal orientation for reduced eddy currents qualify it under this tariff item.
M15 Grain-Oriented Silicon Electrical Steel Sheet
Flat-rolled grain-oriented silicon electrical steel with 3% silicon content, 800 mm wide and 0.30 mm thick, optimized for minimum core loss in transformers. The width over 600 mm and grain-oriented structure meet the criteria of this tariff item.
M4 Grain-Oriented Silicon Steel Coil
High-permeability M4 grade grain-oriented silicon electrical steel coil, 1000 mm wide and 0.27 mm thick, used in distribution transformer cores. Its flat-rolled form, width over 600 mm, and grain-oriented alloy composition qualify it under this tariff item.
