Product Details

Available GOES Grades

Standard	Typical Grades	Application
ASTM A876	M-2, M-3, M-4	Transformer cores (USA, global)
JIS C2553	30Z155, 27Z130	Japanese transformer manufacturers
EN 10107	M0H, M3H, M5H	European high-grade transformer steel
IEC 60404-8-7	CGO, HGO	International classification

Types of GOES We Supply

1. Conventional Grain-Oriented (CGO)

Used in general-purpose transformers, offers balanced cost and performance.

2. High Permeability Grain-Oriented (HGO)

Improved magnetic induction and lower core loss, widely used in energy-efficient and low-noise transformers.

3. Laser-Scribed GOES (Hi-B / Ultra HGO)

Enhanced domain refinement for ultra-low loss applications; enables compact and efficient transformer design.

Processing & Surface Coating

GOES is supplied with insulation coatings suited for transformer manufacturing:

C-5 (Fully Insulated) – High resistance, heat-resistant coating
C-9 (Semi-Insulated) – Balance between insulation and weldability
Phosphate or Organic Coatings – For specific lamination bonding applications

We provide both un-slitted coils and ready-to-stack laminations.
