FAQ

Q:What is the main difference between GO and NGO electrical steel in simple terms?
A:The simplest difference is direction. Grain-Oriented (GO) steel is like a highway, offering super-low energy loss in one specific direction, making it perfect for power transformers. Non-Grain-Oriented (NGO) steel is like a city grid, offering good, uniform performance in all directions, making it ideal for rotating equipment like electric motors and generators.

Q:Which steel is better for transformers?
A:For power and distribution transformers, Grain-Oriented (GO/CRGO) steel is always the better choice. Its directional grain structure is specifically designed to minimize core loss in the transformer core, leading to higher efficiency and less wasted energy over the transformer’s lifespan.

Q:Why is Non-Oriented (NGO) steel used for electric motors?
A:Electric motors require a magnetic field that constantly changes direction as the motor rotates. NGO steel’s uniform magnetic properties in all directions (isotropy) ensure that the motor runs smoothly and efficiently, regardless of the direction of the magnetic flux.

Q:Which type of electrical steel is more expensive?
A:Grain-Oriented (GO) steel is typically more expensive than Non-Oriented (NGO) steel. This is due to its more complex and precise manufacturing process required to align the grain structure. However, its higher efficiency in transformers often results in long-term energy savings that justify the initial cost.

Q:Can you supply specific grades like 23QG090 or 50H470?
A:Yes. As a specialist supplier, GNEE Steel offers a wide range of specific grades for both GO and NGO electrical steel, including common grades like 23QG090 for transformers and 50H470 for motors. We can provide technical data sheets for each grade. Contact us with your required grade for a quote.

Q:Do you offer slitting services for electrical steel coils?
A:Of course. We offer professional slitting and cut-to-length services. We can convert wide electrical steel coils into strips or custom-sized sheets based on your specific core manufacturing requirements. This service helps you reduce waste and streamline your production process.
