M4 Grain-Oriented Silicon Steel Coil from China
High-permeability M4 grade grain-oriented silicon electrical steel coil, 1000 mm wide, 0.27 mm thick, used in distribution transformer cores. Falls under HTS 7225.11.00.00 due to its alloy steel composition with oriented grains for superior magnetic performance. The wide format (>600 mm) distinguishes it from narrower electrical steels.
