Application Demand: Generators, Power Grids, Reactors, and Charging Piles

Silicon steel demand in 2026 is concentrated in four application areas.

Generators. Non-oriented silicon steel laminations form the stator and rotor cores of power generators and industrial motors. Ultra-thin gauge material is increasingly preferred for high-frequency machines to reduce eddy-current losses. According to SMM Analysis, ultra-thin gauge silicon steel below 0.25 mm is the preferred choice for high-frequency motors in new energy vehicles to maximize power density.

Power grids. Grain-oriented silicon steel is the core material for distribution and power transformers. Grid operators in Europe, North America, and Latin America are upgrading transformer fleets under energy-efficiency regulations, including the EU ecological design regulations. High magnetic induction grain-oriented grades such as 23R075 (0.23 mm, iron loss no greater than 0.75 W/kg at 1.7 T and 50 Hz) and 27Q120 (0.27 mm, iron loss no greater than 1.20 W/kg) are available for transformer core applications.

Reactors. High-voltage direct current transmission requires converter transformers and reactors built with ultra-low-loss oriented silicon steel. Application requirements documented for large HVDC converter transformer projects include magnetic flux density of at least 1.92 T and iron loss below 0.85 W/kg under continuous 24-hour load.

Charging piles. EV charging infrastructure is a growing demand driver. The EV charging station and pile market was valued at USD 3,927.96 million in 2024 and is expected to grow at a 32.1 percent compound annual rate, according to Research Nester, significantly increasing demand for silicon steel components in power conversion and distribution equipment.

Variable-frequency and industrial equipment.

Application specifications can also include environmental durability requirements. In coastal areas, insulation coating weather resistance may need to satisfy salt-spray conditions; in cold regions, magnetic permeability retention at extreme low temperatures is specified alongside low iron loss. These requirements push suppliers to combine magnetic performance with coating quality and environmental durability.

Company Statement

In its corporate profile, HL AND SL LIMITED describes its operating approach as adherence to “the principles of comprehensive material selection, competitive pricing, and rapid response,” built on “strong upstream resource integration capabilities and processing support services.” The company states that it provides “one-stop electrical steel procurement solutions” and can supply both high-grade grain-oriented silicon steel and cost-effective non-oriented silicon steel precisely to order.

Market Impact

Chinese suppliers are extending domestic steelmaking scale into export competitiveness. The authorization relationship between HL AND SL LIMITED and China Baowu Steel Group illustrates how trading and processing companies broaden the reach of Chinese electrical steel into overseas transformer and motor supply chains.

In Latin America, oriented silicon steel is widely used in local transformer production at WEG Brazil under INMETRO energy-efficiency certification requirements. Project-level specifications for tropical operating conditions — high humidity, continuous 24-hour full-load operation, and material such as 27Q120 — show how Chinese-origin GO steel is embedded in regional grid infrastructure programs.

For international buyers, the practical consequence of a more integrated Chinese supply chain is faster access to specification-matched material. Processing services that prepare steel to specified size, shape, and performance shift part of the manufacturing burden from the transformer maker to the material supplier, shortening production cycles and reducing waste.

Closing Outlook

The global grain-oriented silicon steel market is projected to grow at a compound annual rate of 5.8 percent through 2035, while the broader electrical steel market is expected to expand from USD 31.0 billion in 2025 to USD 47.0 billion by 2033. China’s position is anchored by integrated producers such as Baosteel, TISCO, Maanshan Iron & Steel, and Ansteel, and extended by export-focused processors such as HL AND SL LIMITED.

As grid modernization, EV charging infrastructure, and stricter transformer efficiency standards continue to drive demand, the competitive advantage is likely to shift toward suppliers that combine product-grade breadth with processing precision and international logistics capability.
