SECTION 1: CORE DIFFERENCES EXPLAINED
| Property | ||
|---|---|---|
| 1–6.5% Silicon, <0.005% C | 0.05–1% C, <0.4% Si | |
| Grain-oriented (GOES) or non-oriented (NGOES) | Ferrite/pearlite/carbides | |
| Manage magnetic flux, ↓ core loss | Structural integrity | |
| 1–7 W/kg | 25–50 W/kg | |
| 1,500–40,000 H/m | 200–1,000 H/m | |
| Silicon content (+$3.50/kg per 1% Si) | Carbon/alloying elements |
Material science insight: Silicon ↑ electrical resistivity 5x, ↓ eddy currents 60%
SECTION 2: APPLICATION-SPECIFIC COMPARISON
Transformer Cores (50Hz Operation)
| 99.2% (No-load loss: 65 kW) | 85% (No-load loss: 400 kW) | ↓ 525,000 kWh/year savings | |
| 72 tonnes | 185 tonnes | ↓ 61% material usage | |
| $2.9M | $6.3M | CRGO saves $3.4M |
Huaxiao Solution:
| 18 W/kg @ 400 Hz | 210 W/kg | ↓ 92% → +5.3% WLTP range | |
| Stable to 25,000 RPM | Lamination failure at 8,000 RPM | Enables 800V architectures |

SECTION 3: HUAXIAO-ALLOY'S SPECIALIZED PRODUCT RANGE
Where Electrical Steel Excels:
| 0.27mm, P₁.₇/₅₀ ≤0.85 W/kg | Power transformers (>99% eff) | |
| 0.30mm, P₁.₀/₄₀₀ ≤20 W/kg | 200kW+ EV traction motors | |
| Salt spray resistance >1,500 hrs | Offshore wind generators |
| Yield: 345 MPa, CE <0.46 | Crane structures, frames | |
| ABS-certified, impact @ -40°C | Shipbuilding | |
| UTS: 950 MPa, HRC 28 | Shafts, gears |
SECTION 4: SELECTING THE RIGHT MATERIAL
Use Electrical Steel When:
- 10,000 magnetic polarity cycles/year (motors/transformers)
- Energy loss reduction delivers ROI <4 years
- OEM specifications mandate IEC/ASTM compliance
- Designing for high-frequency operation (>400 Hz)
- Static load-bearing is primary function
- Material cost > performance savings
- Weldability/machinability are critical
- Operating temperatures exceed 750°C
CONCLUSION: ENGINEERING-DRIVEN VALUE CREATION
Electrical steel isn’t “better” steel – it solves fundamentally different problems.
Electrical Steels: Zero-comproise magnetic performance Structural Steels: Optimized mechanical properties Hybrid Systems: Clad metals for electromagnetic-structural integration.
