Market Insight: Grain Oriented Electrical Steel Price in Power Industry
Market Analysis: Sourcing High-Quality Grain-Oriented Electrical Steel
Industrial Demand Drivers
Global demand for grain-oriented electrical steel (GOES) is driven by grid modernization, renewable energy integration, and stringent efficiency regulations. Transformers—critical to power transmission—account for 60% of GOES consumption. With Asia-Pacific leading infrastructure expansion (projected 4.8% CAGR through 2028), utilities and manufacturers prioritize high-efficiency designs compliant with IEC 60076 standards. Rising energy costs and carbon reduction targets further accelerate demand for low-loss GOES in distribution and power transformers.
Material Quality Impact on Efficiency
Core losses in transformer cores represent 60–70% of no-load losses. High-quality GOES with precise grain orientation minimizes hysteresis and eddy current losses at operating flux densities (e.g., 1.7T). A 0.1 W/kg reduction in core loss improves transformer efficiency by 0.15–0.25%, yielding $50,000+ in lifetime energy savings for a 100 MVA unit. Substandard materials cause thermal degradation, insulation breakdown, and premature failure—directly impacting operational reliability and maintenance costs.

Technical Specs: Grain Oriented Electrical Steel Price Parameters
Critical Technical Specifications for Grain-Oriented Electrical Steel
Core Loss & Magnetic Flux Density
Grain-oriented electrical steel (GOES) performance hinges on core loss (iron loss) and magnetic flux density. Core loss, measured in W/kg at 1.7T/50Hz per IEC 60404-3, directly determines transformer efficiency and operational energy costs. Lower values reduce no-load losses, critical for high-efficiency power systems. Xinzhaohe’s GOES achieves ≤1.05 W/kg at 1.7T/50Hz—surpassing IEC standards (≤1.10 W/kg). Magnetic flux density at 800 A/m exceeds 1.90 T, outperforming industry benchmarks (≥1.88 T). This is achieved through proprietary silicon content optimization (3.0–3.2%) and precise grain orientation during annealing, ensuring optimal performance in renewable energy and grid infrastructure applications.
Lamination Flatness & Insulation Coating
Lamination flatness (≤0.06 mm/m) is essential for stacking factor optimization. Tighter tolerances minimize air gaps, reducing eddy current losses and enhancing magnetic efficiency. Insulation coatings (C-4/S-5 per IEC 60404-8) provide dielectric strength >250 V and thermal stability up to 200°C. Xinzhaohe applies uniform, high-adhesion coatings via continuous annealing lines, ensuring corrosion resistance and long-term reliability in high-temperature environments.
| Specification | Industry Standard (IEC/ASTM) | Xinzhaohe Performance |
|---|---|---|
| Core Loss (W/kg) @ 1.7T, 50Hz | ≤1.10 (IEC 60404-3) | ≤1.05 |
| Magnetic Flux Density (T) @ 800 A/m | ≥1.88 (IEC 60404-3) | ≥1.90 |
| Lamination Flatness (mm/m) | ≤0.08 (IEC 60404-8) | ≤0.06 |
| Insulation Coating Type | C-4, S-5 (IEC 60404-8) | C-4, S-5, Customizable |
