Non-oriented electrical steel grades
The LG/L series on this page are reference grades from the original mill manuals, not Baosteel grades. Baosteel supply grades, properties and specifications are subject to official Baosteel documentation, the quotation and the mill test certificate for the relevant batch.

Insulation coating
C — semi-organic (Cr-containing), 0.3–0.7 µm · H — semi-organic, chromium-free, 0.3–1.2 µm. Both give good adhesion, corrosion resistance, punchability and weldability.
