Electrical Steel in 2026: Top Application Trends Reshaping Transformer and Motor Procurement
Electrical Steel in 2026: Top Application Trends Reshaping Transformer and Motor Procurement
Electrical steel is evolving from a commodity input into a performance-defining material for transformers, electric motors, generators, and new energy vehicles. For procurement teams in 2026, the practical question is no longer just what grade to buy, but which application trend will determine future supply, specification, and cost requirements.
Why Electrical Steel Application Trends Matter in 2026
Electrical steel, also known as silicon steel, is a specialized ferromagnetic material used to build magnetic cores in equipment that converts and controls electrical energy. Its two main families are grain-oriented electrical steel (GOES), used primarily in transformer cores, and non-oriented electrical steel (NOES), used in rotating machines such as motors and generators.
In 2026, procurement decisions are being shaped by three structural shifts: the global push for higher energy efficiency, the rapid expansion of electric vehicles, and the modernization of power grids. These shifts change not only which products need electrical steel, but which performance parameters buyers must prioritize.
Market Growth Signals for Electrical Steel
The global electrical steel market was valued at USD 31.0 billion in 2025 and is projected to reach USD 47.0 billion by 2033, growing at a CAGR of 5.5% from 2026 to 2033 (Grand View Research). China's electrical steel production reached 16.1 million tonnes in 2024, a 5.4% year-on-year increase (Chinese Society for Metals via MarketReportsWorld). China's export volume of grain-oriented electrical steel reached 393,200 mt in the first half of 2025, up 16.0% year-on-year (Shanghai Metals Market).
These figures point to a market that is not only expanding but also becoming more globalized. For buyers, the practical implication is that supplier selection now includes export reliability, processing capability, and application knowledge, not only material specifications.
How Application Trends Are Reshaping Material Requirements
1. Transformer Applications: Lower Core Loss, Higher Flux Density
Transformers remain the largest single application for grain-oriented electrical steel. Core loss directly affects a transformer's lifetime efficiency, and magnetic flux density affects how compact and cost-effective the core can be.
In high-efficiency power transformers, common selections include 23Q080 and 23Q085 grades. The 23Q080 grade offers a maximum iron loss of 0.80 W/kg at P₁.₇/₅₀, with typical measured values between 0.76 and 0.78 W/kg, and a magnetic flux density of at least 1.89 T. The 23Q085 grade provides a maximum iron loss of 0.85 W/kg and a flux density of at least 1.88 T.
For ultra-high voltage and energy-saving transformer cores, thinner Hi-B (high magnetic induction) grades such as 20R070 and 20-65 are becoming more common. The 20R070 grade is 0.20 mm thick, with iron loss ≤ 0.70 W/kg and flux density ≥ 1.86 T. The 20-65 grade offers iron loss ≤ 0.65 W/kg at the same thickness. These grades help manufacturers meet stricter efficiency regulations without enlarging core dimensions.
For photovoltaic DC converter transformers and industrial frequency conversion equipment, 27Q095 offers a balance of thickness, loss, and flux density, with B₈ ≥ 1.91 T.
2. Motor and Generator Applications: Non-Oriented Grades and High Efficiency
Motors and generators require non-oriented electrical steel because the magnetic flux changes direction as the rotor turns. The key parameters for these applications are low core loss under alternating magnetization and good permeability across a range of operating frequencies.
Non-oriented electrical steel must conform to standards such as ASTM A677 for core loss (e.g., grades M15, M19, M22) and magnetic permeability in North America, and IEC 60404-8-4 for cold-rolled non-oriented strip and sheet globally. Buyers evaluating suppliers for motor applications should verify that the proposed material can be traced to these recognized standards.
For motor and generator procurement, the practical sourcing challenge is often less about standard grades and more about consistency across batches, because motor manufacturers integrate stamped laminations into high-volume production lines.
3. New Energy Vehicles: The Fastest-Growing Demand Segment
Non-grain-oriented electrical steel consumption for the automotive sector, specifically EVs, accounted for over 34% of total demand in 2024 (Precedence Research). Traction motors in EVs operate at high frequency and high power density, which pushes material requirements toward thin gauges, low loss, and high permeability.
This trend has a direct effect on supplier capability requirements. High-volume EV programs need consistent coating quality, precise thickness control, and reliable cutting or stamping. Buyers who source electrical steel for EV motors should evaluate whether the supplier can support custom processing, not only standard coil supply.
4. Household Appliances: Cost-Effective Efficiency
Household appliance motors operate under less extreme conditions than EV traction motors, but the sheer volume of units makes efficiency improvements highly valuable across a product line. For this segment, buyers typically balance iron loss, price, and processing simplicity. Standard non-oriented grades with stable batch-to-batch performance are usually preferable to premium grades that add cost without meaningful efficiency gains in the final application.
5. Generator Applications: Durability Under Continuous Operation
Generators require materials that maintain stable performance over long operating hours and frequent load changes. Low iron loss and high flux density reduce heat and improve output efficiency. Buyers for generator projects often prefer grades that have documented application history in power equipment, because reliability evidence is as important as datasheet values.
Evaluating Supplier Capabilities for Application-Specific Procurement
Specification Customization
For transformer and motor manufacturers, the availability of specific thickness and width combinations is often the first screening criterion. A supplier that can customize thickness from 0.18 mm to 0.35 mm, and width from 800 mm to 1250 mm, including an ultra-wide 1250 mm specification, provides more design freedom for core designers.
Material and Coating Options
Application requirements also determine material and coating selection. General grain-oriented CGO grades, high magnetic flux Hi-B grades, laser-engraved R series, and heat-resistant engraved HS series each serve different transformer designs. Coating options include organic coating (temperature resistance ≤ 180℃), inorganic coating (up to 800℃), and semi-organic coating. Inorganic coating is especially relevant for applications that require stress-relief annealing after cutting.
Processing Capability
Many buyers now prefer suppliers that can deliver processed material, not only master coils. Strip cutting, fixed-length flat cutting, and longitudinal cutting reduce the buyer's need to invest in additional slitting lines. For lamination-intensive applications, custom stamped electrical steel can shorten the path from material to finished core.

Case Evidence: How Electrical Steel Grades Perform in Real Transformer Production
Application evidence helps buyers judge whether a supplier's materials perform outside the datasheet. A transformer manufacturer in Mexico uses oriented silicon steel supplied by HL AND SL LIMITED for the production of iron cores for power transformers, converter transformers, and special engineering transformers worldwide. The project covers batch supply for complete power transmission and distribution transformer manufacturing, with an annual business scale of approximately USD 500 million. The material has been in stable operation for over 10 years.
In Brazil, the electrical equipment manufacturer WEG has applied supplied materials to the local production of power transformers and distribution transformers since 2010. The large-scale application has been verified in stable operation for over 10 years and has helped WEG meet local grid energy efficiency standards and low-carbon transformation requirements. Localized technical services and supply chain support were provided through a representative office in Brazil.
These two cases demonstrate different value dimensions. The Mexico case shows sustained performance in high-value, complex transformer production. The Brazil case shows how supplier support structures can help a large manufacturer meet regulatory and sustainability goals at scale.
Supplier Selection Considerations for Application-Led Procurement
Production and Lead Time
For evaluation-stage buyers, supplier capacity and lead time are critical decision factors. A monthly capacity of 4000 tons supports regular orders with lead times of 15–20 days, urgent or stock orders in 3–7 days, and bulk export orders arriving at port in 30–45 days. The minimum order quantity is 25 tons.
Quality Assurance
Buyers should confirm how the supplier verifies material quality. Standard quality control practices include origin inspection at the factory, batch inspection reports, material certificates or warranty certificates delivered with the goods, and optional third-party testing through CMA/CNAS-accredited laboratories. These measures support traceability for transformer and motor manufacturers who need documented evidence for their own compliance records.
After-Sales and Technical Support
Material performance issues often appear only during cutting, stamping, annealing, or final testing. A supplier's after-sales process matters. Service commitments include lifecycle-wide technical guidance, inbound quality inspection dispute handling, re-inspection processing, and a feedback loop of 1–3 working days for abnormalities or customer complaints.
Step-by-Step: Building an Application-Based Electrical Steel Evaluation
Buyers can use the following framework to align material choice with the end application.
- Define the operating condition. Determine frequency, flux density, core geometry, and efficiency target for the end device.
- Translate the condition into material parameters. Select candidate thickness, iron loss, flux density, and coating type from verified specifications.
- Check the applicable standards. Verify whether the grade needs to comply with standards such as ASTM A677 or IEC 60404-8-4 for the destination market.
- Evaluate processing compatibility. Consider whether strip cutting, longitudinal cutting, or custom stamping is required before core assembly.
- Assess supplier evidence. Review documented application cases, quality control procedures, and response commitments.
- Compare total cost and risk. Account not only for material price but also for lead time, processing cost, and the cost of performance failure.
