Non-Oriented Electrical Steel

Product Overview

Non-Oriented Silicon Steel (NOES) is a mainstream soft magnetic alloy material without grain orientation. Its isotropic magnetic property delivers stable permeability in every rolling angle. It is the core raw material for rotating electrical equipment, covering industrial motors, new energy motors, household appliances and power generators to reduce iron loss and boost energy efficiency.

FAQ Frequently Asked Questions

Q: What is the difference between non-oriented and grain oriented silicon steel?

Non-oriented steel has uniform magnetism for rotating motors. Grain oriented steel has superior performance along rolling direction for static transformers.

Q: Can you provide free test samples?

Small cutting samples are available for lab performance testing, only international freight cost needs to be covered by buyers.

Q: What is your minimum order quantity MOQ?

Full coil MOQ for raw material; small batch cut sheets are acceptable for trial orders, full container recommended for export cost saving.

Q: Can you support third-party factory inspection?

Factory on-site inspection, SGS/BV third-party lab testing is available upon buyer’s request before shipment.
