Electrical steel grades (GB/T, JIS, EN, ASTM), Epstein & SST test data, transformer core design basics, motor lamination stamping, export logistics.

Core loss modeling for high-frequency motor laminations, IEC 60404 test methods, and how thin-gauge NGO grades (0.20–0.27mm) perform in EV traction motors.

Writing practical guides on silicon steel: grade comparisons, core loss vs. thickness, and buyer checklists for transformer and motor manufacturers.

Questions on CRGO/CRNGO grade selection, transformer core and motor lamination sourcing, slitting/cut-to-length specs, and electrical steel export from China.
