1. Product Characteristics

Cr-Free Insulation Coating
Base Metal (Fe-Si)
Cr-Free Insulation Coating

This is a non-oriented electrical steel with a Cr-free insulation coating widely used in core manufacturing.  Such properties as insulation, corrosion resistance, and drawability are comparable to those of conventional coating materials (C6-A,B) while coating adhesion is superior.  It is worth noting that this coating is environmentally friendly with no addition of Cr 6+, which is hazardous to human health and the environment.
