Choose grain-oriented steel by certified magnetic performance and the geometry of the transformer core—not by grade name alone.
Request the supplying mill datasheet and confirm whether the quote is for a 23Q110 designation or a verified B23G110 correspondence. Check the current contractual standard.
State ≤1.10 W/kg only when adopted as the contractual loss target, with defined measurement, sampling and delivery state.
Request the guaranteed B800 level and actual test result. Different producer documents and standard editions can publish different induction figures.
Supply transformer limb and yoke drawings, strip widths, miter angles and the intended rolling direction of each component.
Specify coating class, surface resistance, adhesion, stack-factor target and any permitted stress-relief treatment.
Link material identification to coil numbers, magnetic testing, finished slit width, edge burr and trial-core requirements.
Send your 23Q110 specification, loss/induction limits, drawing and annual volume in one RFQ.
The insulating surface, adhesion, stacking factor and compatibility with cutting or core assembly affect transformer performance and production yield.
Replace this image with a genuine close-up of the actual GO steel coating, preferably showing surface texture and roll identity.
Grain-oriented electrical steel is supplied with a mill-approved surface insulation system that helps limit interlaminar currents. Coating construction and surface resistance must match the transformer assembly method and processing conditions.
For transformer cores, strip width and rolling-direction consistency are as important as thickness and magnetic certificate values.
Specify finished strip width, thickness tolerance, edge quality and rolling-direction marks needed for your core-piece layout.
Include limb/yoke dimensions, 45° mitre or step-lap details and the permitted burr height with your stamping or shearing drawing.
Conventional GO electrical steel has strongly directional magnetic performance. Define the steel rolling direction in each core piece and in acceptance sampling.
Verify steel gauge, coating-inclusive dimensions if relevant, residual curvature, edge wave and strip flatness against the cutting line.
Specify edge burr, slit cleanliness and handling damage limits; assess stress introduced by shearing in the transformer-core qualification.
Confirm inner diameter, winding direction, strip orientation, telescoping limits and surface protection for the receiving equipment.
Plan the processing route around directional grain structure and the coated surface. Each cut should preserve traceability to the original magnetic test lot.
Submit core-strip widths, cut lengths, limb/yoke drawing, joint geometry, rolling direction and annual transformer quantities.
Approve the exact 23Q110 or documented producer designation with the magnetic test limits and insulating coating.
Quote slit widths, width tolerance, edge burr limits, winding tension and separate-coil labels.
Run shearing or cut-to-length trials, inspect burr and direction marks, and evaluate the assembled core against its required losses.
Include strip orientation, slit widths, cut lengths, burr limits and target core losses for quotation.
Coordinate grain-oriented steel selection with the transformer-core design rather than relying on nominal thickness alone.
23Q110-class conventional GO steel is selected for core laminations where magnetization predominantly follows the rolling direction. Final grade approval should consider the transformer design, service frequency, assembled-core losses and processing route.
Laminated transformer cores where specified 50 Hz no-load loss and induction values are critical procurement measures.
Slit limb and yoke strips cut to customer magnetic circuit drawings and agreed steel performance.
Approved parent coils and slit strips for mitre-cut, step-lap and core assembly work.
Core strip purchased by magnetic class, stack geometry, test conditions and electrical insulation requirement.
Matching existing core designs by grade designation, coating, orientation and magnetic MTC.
Lot-based procurement scheduling with consistent width, inspected coating and documented core-loss values.
Estimate available strip length and a preliminary lamination quantity before specifying your coil mass, width and core-cutting dimensions.
Estimate net coil length, strip mass per meter, theoretical cut pieces, and laminations within a target stack height. Use steel-only gauge and confirmed net mass.
All quantities are estimates for planning. Coating mass, coil core, edge trimming, blade kerf, joint geometry, magnetic stress and production scrap require project-specific adjustment.
Calculating...
Production and final surface control determine the magnetic performance that the supplying mill certifies. Your order should identify the approved source and processing condition.
Conventional grain-oriented electrical steel is produced through controlled rolling and annealing steps designed to develop a preferred magnetic texture. The final surface insulation and handling condition are integral to core-making performance.
Coordinate approved material grades, coil dimensions, quality documents and delivery terms for transformer manufacturing.
The company operates across multiple steel product families. Overall production capacity and regular inventory are business-wide metrics, separate from 23Q110 grade availability.
Compare grade designation, P1.7/50, B800, thickness tolerance, rolling direction and surface coating in one quotation.
Request material records tied to source mill, coil or heat identification and the contracted magnetic test report.
Plan slit coils, wrapping, edge guards and delivery details around your transformer manufacturing and receiving line.
Share your mill approval list, loss class, annual tonnage, coil dimensions and target delivery schedule.
Select certified 23Q110 material using the agreed magnetic test method, defined direction, coating system and coil-by-coil identification.
Request a mill certificate identifying the material, the accepted core-loss class and the actual induction data. With grain-oriented steel, the test direction and sample treatment matter to the reported loss.
Choose processing steps from the approved mill condition and downstream core-piece drawings. Scope and feasibility are confirmed in the quotation.
Confirm parent-coil availability, finished slit width, tolerance, cut-edge burr and winding orientation before processing.
Where offered, arrange sample sheet or step-lap / mitre-cut components based on your drawing and cutting setup.
Control scratches, debonding and edge condition while moving or packaging coated grain-oriented steel.
Carry original lot number, source-mill designation and magnetic report identifiers into processed slit-coil labels.
Confirm the actual source mill, magnetic properties and finished-coil format before making stock or delivery commitments.
The availability of a conventional 0.23 mm GO grade depends on the producing mill, magnetic class, surface coating, slit width and order volume. Company-wide steel inventory does not imply verified 23Q110 stock.
Coordinate coil handling and shipment protection with your receiving factory and transformer-core manufacturing requirements.
Electrical steel coils need careful protection from moisture, excessive handling stress and damage to slit edges or insulation coating. Specify packing based on coil mass, unloading equipment and shipping route.
Match material directionality to your machine type. Transformer-core oriented strip and non-oriented motor lamination strip serve different magnetic circuit designs.
Frequently requested specifications for conventional GO transformer-core strip, source-mill qualification and international coil procurement.
23 is the nominal 0.23 mm thickness, Q identifies the conventional grain-oriented grade designation in the referenced catalogues, and 110 denotes a P1.7/50 loss class of 1.10 W/kg. Confirm the supplying mill grade and guaranteed values on its technical specification and MTC.
GB/T 2521.2-2025 is the current Chinese specification for fully processed grain-oriented electrical steel strip. It replaced the 2016 edition on 1 March 2026. The contract should confirm whether the supplier uses the 23Q110 designation or a verified mill grade mapping.
