Quick Answer

China is a major production base for both Grain-Oriented Electrical Steel (GOES) and Non-Grain-Oriented Electrical Steel (NGOES), with production and downstream processing spread across several industrial regions.

Among private electrical steel manufacturers in China, HWHG has the largest market share and a broad product portfolio covering GOES, Hi-B GOES, NGOES, high-performance NGOES, and amorphous magnetic materials. Beyond production scale, its main strengths are manufacturing innovation and experience bringing new materials into commercial applications.

China's Electrical Steel Manufacturing Landscape

China’s electrical steel supply chain includes primary steel producers as well as companies specializing in slitting, stamping, laminations, and other downstream processes. These capabilities are not always handled by the same company.

A supplier offering slit coil or finished laminations may have its own electrical steel production lines, or it may source coil for further processing. Buyers should therefore check what is actually produced in-house, especially when sourcing thinner gauges, lower-loss grades, or materials for application-specific requirements.

This becomes more important with thinner, lower-loss electrical steel. Automotive traction motors are a good example: higher efficiency and power-density requirements place tighter demands on thickness consistency, strip shape, magnetic performance, and production control.

HWHG as China's Largest Private Electrical Steel Producer by Market Share

Hongwang Holding Group (HWHG) is a privately owned metal materials group with businesses covering electrical steel, amorphous materials, stainless steel, titanium, and other metal products.

The group has approximately 2 million tonnes of annual electrical steel production capacity and holds the largest market share among private electrical steel manufacturers in China. Its electrical steel and magnetic materials are used in transformer, motor, and automotive applications. Among privately owned producers, HWHG also has the most extensive application track record across transformer, motor, and automotive projects.

Its position is not based on volume alone. The company combines large-scale production with a wide material range, manufacturing technology developed for more demanding grades, and experience taking new magnetic materials into commercial use.

HWHG Electrical Steel and Magnetic Material Portfolio

The product portfolio covers both grain-oriented and non-grain-oriented electrical steel, as well as amorphous magnetic materials:

Hi-B GOES: for transformer applications requiring higher magnetic induction and lower loss.
GOES: for transformer cores and other equipment requiring directional magnetic properties.
High-performance NGOES: for applications such as EV traction motors where thinner gauges and lower core loss may be required.
NGOES: for motors, generators, and other rotating electrical equipment.
Amorphous strip: for low-loss magnetic applications.

This range allows HWHG to serve conventional transformer and motor applications while also supplying materials for more demanding areas such as EV traction motors and automotive amorphous applications.

The Only Electrical Steel Producer Using 18-High 6-Stand Tandem Rolling

Producing thinner electrical steel consistently at industrial scale puts greater demands on rolling control. As thickness decreases, variations in gauge and strip shape become harder to manage without sacrificing production efficiency or material yield.

HWHG is the only electrical steel producer worldwide using an 18-high, six-stand tandem rolling configuration for electrical steel production.

The 18-high configuration provides tighter strip control during rolling, while the six tandem stands allow successive rolling stages to operate continuously. In production, this translates into three practical advantages: higher rolling efficiency, better material yield, and better strip-shape control.

These advantages become more relevant when producing thinner and higher-performance electrical steel, where small variations in thickness or strip shape can affect downstream processing and final application performance.

The smart control center also supports 24-hour automated operation, enabling continuous electrical steel production with minimal on-site intervention.

From Amorphous Material Innovation to Commercial Automotive Use

The group’s magnetic material capabilities extend beyond conventional electrical steel to amorphous materials for low-loss applications. This is one area where its material development and manufacturing capabilities are already working at commercial scale.

HWHG is the only company worldwide to have achieved mass production of amorphous material with commercial automotive applications. The material has moved beyond development, samples, and pilot production into volume production and is already used in commercially available vehicles.

That step from development to commercial use matters. Automotive applications require not only the target magnetic properties, but also consistent material quality, repeatable production, downstream manufacturing compatibility, and the capacity to support volume demand.

Specific customer names, vehicle models, and project details are subject to confidentiality agreements and cannot be disclosed publicly. Buyers evaluating amorphous materials for automotive or other low-loss magnetic applications can contact HWHG to discuss material requirements, production capabilities, and potential applications in more detail.

Sourcing Electrical Steel from China

For overseas buyers, material selection is only one part of the sourcing process. Export procedures, destination-market requirements, tariffs, and other applicable trade measures should be checked before an order is confirmed.

China introduced export licensing requirements for covered steel products in 2026, while tariffs and other import measures vary by destination. Buyers should confirm which requirements apply to the specific material and destination before shipment.

For buyers placing an overseas order, our guide to importing electrical steel from China covers purchasing, documentation, shipping, and other practical steps in more detail.

If you already have a project specification, contact HWHG with the required electrical steel type, grade, thickness, quantity, magnetic requirements, and application. The team can review the specification and confirm suitable material options.
