Overview

Cold-rolled non-oriented electrical steel has magnetic properties intended to be comparatively uniform in the plane of the sheet. It is commonly specified for laminations in motors, generators, compressors, and related rotating electrical equipment. An order needs an exact grade and governing standard because the grade designation links nominal thickness and magnetic-property limits to defined test conditions. Buyers should state thickness, width, coil or sheet form, insulation coating class, maximum specific total loss, minimum magnetic polarization or induction where required, dimensional tolerances, coil data, and inspection documents. Transformer-core material should be reviewed separately when grain-oriented electrical steel is required. Final grade selection depends on the equipment design, lamination process, and agreed test basis. Coil handling and edge requirements should also be agreed before order acceptance.

Product scope

Non-oriented electrical steel is separated from grain-oriented transformer steel.
Magnetic properties are stated with the ordered grade and test conditions.
Grade, coating, dimensions, and magnetic test conditions are treated as separate order fields.

Applications

Motor and generator laminations
Compressor and pump motor cores
Rotating electrical-machine cores selected by the equipment designer

Surface options

Electrical insulation coating specified by class
Surface condition and coating compatibility confirmed for the lamination process

Processing & form

Coil or sheet form by order
Slitting requirements stated with edge and burr limits

FAQ

What should the RFQ for Cold-Rolled Non-Oriented Electrical Steel include?

State Governing standard and exact electrical-steel grade, Nominal thickness and width, Coil or sheet form and coil data, Insulation coating class, Core-loss and magnetic-polarization test basis, Quantity and destination port. Technical availability is confirmed only after the complete order basis is reviewed.

Do reference standards confirm available grades and sizes?

No. A reference standard defines the product and test basis. Grade, size, processing, testing, documents, and shipment availability remain order-specific until confirmed in the offer.

What information is needed to quote Cold-Rolled Non-Oriented Electrical Steel?

Send the required grade or standard, dimensions, quantity, destination port and application. Add surface, processing, packing or inspection requirements when they affect the order.

How should I select the grade or standard for Cold-Rolled Non-Oriented Electrical Steel?

Use the project specification and end use as the starting point. Share any required reference such as IEC 60404-8-4, EN 10106, GB/T 2521.1, together with forming, welding, corrosion or service conditions, so the quotation follows the intended application.

What affects the quotation for Cold-Rolled Non-Oriented Electrical Steel?

The material specification, dimensions, quantity, processing, surface, packing and destination all affect the quotation. Final commercial terms are provided against the submitted RFQ.

How is Cold-Rolled Non-Oriented Electrical Steel prepared for sea shipment?

Packing is selected for the Coil form, dimensions, handling method and shipping route. State any pallet, bundle, coil orientation, moisture protection or marking requirements in the RFQ.
