At GNEE, we are a trusted exporter of non-grain oriented electrical steels with over a decade of experience serving power generation equipment manufacturers worldwide. We understand that building reliable generators, alternators, and rotating machines requires magnetic steel with consistent core loss, good permeability, and excellent mechanical properties.
Our 50W350/50W600 0.5mm CRNGO (Cold Rolled Non-Grain Oriented) steel helps you achieve higher energy conversion efficiency, lower operating temperatures, and compliance with IEC/GB/T standards. We offer custom slitting, anti-rust packaging, and just-in-time delivery to any global port.
50W350/50W600 CRNGO Power Generation Description
High-grade CRNGO such as 50W350 is essential for large power generation units, while the wind power industry often opts for grades like 50W600, reflecting the specific needs of each energy sector.
Cold rolled non oriented silicon steel sheet is mainly used for generator manufacturing, so it is also called cold rolled motor silicon steel. Its silicon content is 0.5%-3.0%, which is cold rolled to the thickness of the finished product. The supply state is mostly 0.35mm and 0.5mm thick steel strips. The BS of cold-rolled non oriented silicon steel is higher than that of oriented silicon steel; compared with hot-rolled silicon steel, the thickness of cold-rolled non oriented silicon steel is uniform, the dimensional accuracy is high, and the surface is smooth, which improves the filling coefficient and the magnetic properties of the material.
Why 0.5mm CRNGO Steel is Critical for Power Generation Applications
Power generators convert mechanical energy into electrical energy – and core losses directly reduce output efficiency. Using 50W350/50W600 0.5mm CRNGO in stator and rotor cores improves generator performance in three key ways:
Reduced Heat Generation and Longer Life
Lower core loss (W/kg) means less heat inside the generator. For a 500 kVA generator, switching from 50W800 to 50W600 reduces temperature rise by 8–10°C, extending insulation life by nearly 50%.
Improved Power Factor and Voltage Regulation
High magnetic induction (B₅₀ ≥ 1.66 T) allows designers to achieve higher flux density without increasing core weight. This directly improves generator power factor and voltage stability under load.
Excellent Punchability for High-Volume Lamination Stamping
0.5mm CRNGO steel from GNEE is optimized for progressive dies. Typical burr height is ≤ 0.03 mm, and the material accepts high-speed stamping (up to 200 strokes/minute) with minimal tool wear.
