Motor-core designers usually specify magnetic limits and coating requirements along with dimensions. The actual mill standard and verified certificate are essential for this grade name.
All dimensional examples are RFQ fields, rather than a promise of available stock.
Core loss, induction and their test conditions matter more for electrical steel acceptance than a generic carbon-steel tensile table.

Coating performance affects interlaminar current flow, punchability and consistency when multiple stamped laminations are stacked.
Electrical steel is typically supplied with an insulating surface layer selected for the customer's stamping process and core assembly method. Confirm coating chemistry, coating mass and relevant surface-insulation resistance before placing the order.
ASTM A976 groups insulating coatings by composition and use; individual surface-resistance acceptance is a separate contractual requirement. Coating suitability depends on stamping, welding, bonding, temperature exposure and stress-relief practice.
Use actual mill photos to show coating uniformity and coil edges; product performance depends on testing, not appearance alone.
Electrical steel must suit both the magnetic circuit and the physical requirements of high-volume punching and stacking.
Specify required slit width, width tolerance, coil set, edge burr target and compatibility with feeder equipment.
Confirm stacking factor, coating thickness, punched-part geometry and assembly method before large-batch production.
Verify whether the requested 0.35 mm refers to steel substrate or coated overall thickness and cite the tolerance basis.
Provide strip width, coil ID, allowable coil mass, edge shape and required winding direction.
Check how coating, burr, stamping clearance and interlocking details affect the completed magnetic core.
Align coil specifications with the tooling, punching quality and test program used on your manufacturing line.
Share the stator/rotor drawing, gauge, blank dimensions and target motor performance.
Select master coil width or slit strips with dimensional and edge acceptance.
Run customer tool trials and review burr, coating and stack height.
Confirm tested loss and induction from the agreed material lot; validate finished-core losses separately.
Selection depends on operating frequency, core design and certified material data rather than the material name alone.
Non-oriented electrical steel is widely used in rotating machines, where performance across several in-plane directions matters. Select 35W470 according to the motor design, frequency, loss target and approved magnetic test results.
Specify exact steel losses, gauge and stacking requirements against designed motor efficiency.
Confirm production stamping width, coating choice and consistency across deliveries.
Evaluate the applicable flux-density range and frequency before finalizing material selection.
A practical estimate for buying coil tonnage and planning lamination-feeder input. Final stamping yield depends on the customer die and scrap allowance.
Enter the net steel coil mass and actual or agreed material density. Results exclude cores, packaging, winding gaps and slitting scrap.
Reference density of 7.70 g/cm³ is illustrative; confirm the specific silicon-steel mill grade. Blank quantity is theoretical and assumes 100% usable feed length.
This tool estimates steel-strip geometry and does not calculate core loss, actual core output or final stacked-core mass.
Electrical steel requires dedicated magnetic testing and insulating surface control in addition to dimensional checks.
A typical fully processed non-oriented electrical steel route includes controlled rolling, final annealing, insulating-coating application and coil handling. Request the exact supplying mill's process and specification where these affect motor-core qualification.
Use one RFQ to define magnetic acceptance, slitting, inspection and delivery scope. Company scale figures cover the overall steel business, not guaranteed 35W470 output.
Company-wide steel manufacturing and inventory capacity supports sourcing across multiple flat-steel families. Exact 35W470 supply is confirmed separately.

Request sheet lengths or sample blanks for die validation if available for your chosen steel and coating.
Maintain identification of the supplied parent coil, processed strip width and original material test documentation.
Send stamping drawings and blank-feed pitch; tooling validation remains part of the customer’s production process.
Company-wide inventory scale does not establish live stock for a specific electrical-steel magnetic grade.
Inventory and lead time change by source mill, coating, width and quality acceptance. Share the complete material specification to verify a supply route for single orders and recurring deliveries.
Coordinate packing and identification with the quality documentation required by your receiving factory.
Electrical steel surface damage and moisture exposure can complicate downstream lamination manufacturing. Confirm wrapping, handling arrangement and coil labels before international dispatch.
Choose electrical-steel grades by nominal thickness, directionality and certificate-backed magnetic performance.
These answers support preliminary material selection and RFQ preparation; actual test results are tied to the contracted supplying mill and lot.
35W470 is a commercially used designation for 0.35 mm nominal non-oriented electrical steel coil. Verify the mill grade datasheet and magnetic loss/induction limits before ordering.
The “470” commonly expresses a 4.70 W/kg target at 1.5 T and 50 Hz, but this specific commercial grade name requires a mill-approved specification and magnetic test certificate. Include your guaranteed limit in the purchase contract.
GB/T 2521.1-2016 is the current national specification for fully processed non-oriented electrical steel. The applicable grade table and offered mill designation must be checked together; this page does not claim an automatically certified 35W470 entry.
It is a specific total magnetic loss measurement at a reference magnetic polarization/flux-density index of 1.5 T and frequency of 50 Hz, reported in W/kg under the agreed test method.
It is a magnetic induction or polarization parameter at magnetic field strength 5,000 A/m. State the reporting convention and minimum acceptable result when requesting a quotation.
Non-oriented steel is designed for more uniform in-plane magnetic response than grain-oriented material, but the degree of anisotropy still depends on grade and processing.
No direct interchange should be assumed. The nominal base thicknesses are different, and coating, loss, induction, stacking factor and stamping geometry must be evaluated separately.
Coating selection depends on the supplying mill and order. Tell us your intended stacking, welding, bonding or punching method and required resistance; coating class and actual availability will be confirmed in the offer.
Slitting may be available subject to agreed width, edge burr, coating compatibility, order quantity and production arrangements. Provide finished strip dimensions in your RFQ.
Divide net mass in kilograms by the steel strip weight per meter: thickness (mm) × width (mm) × density (g/cm³) × 0.001. Actual results depend on the mill density and coating basis.
Traction motor suitability depends on high-frequency loss, yield strength, core design and motor test targets. Request higher-frequency magnetic data and engineering approval before selecting any general-purpose designation.
Send the grade and mill datasheet, 0.35 mm gauge, strip width, core loss conditions, B50/J5000 requirement, insulation coating, coil mass and ID, total tonnage, test documents and destination.
Send your steel grade sheet, required magnetic loss and induction data, 0.35 mm thickness tolerance, coil width, insulating coating, individual coil mass, total MT and destination. Include lamination drawings and trial-approval requirements where applicable.
