Non-Oriented Electrical Steel, abbreviated as NOES, is a type of electrical steel named for its randomly distributed internal grain structure. NOES materials have essentially uniform magnetic properties in all directions, making them very popular in applications where the magnetic field direction is constantly changing, such as in the manufacturing of electric motors and generators. Zhongxin Special Steel supplies high-quality electrical steel for new energy, industrial manufacturing, and other sectors. Contact us for a free quote!
Properties of Non-Oriented Electrical Steel
Non-Oriented Electrical Steel (NOES) primarily consists of iron (Fe), silicon (Si), and aluminum (Al), with a silicon content ranging from 0.5% to 3.0%, and a uniformly applied insulating coating on the surface. Silicon and aluminum effectively optimize the material’s magnetic and mechanical properties, while the surface insulation layer enhances corrosion resistance, reduces eddy current losses, ensures product stability and reliability, and extends equipment service life.
Mechanical Properties
NOES steel produced by Zhongxin exhibits excellent mechanical properties, including appropriate tensile strength and yield strength, effectively resisting deformation during processing and use.
- The material has good toughness and ductility, making it resistant to cracking and fracturing, and suitable for various complex processing techniques such as stamping, shearing, and bending.
- Uniform hardness distribution avoids performance inconsistencies caused by localized high hardness, ensuring product quality consistency in mass production.
- Good wear resistance and fatigue resistance significantly extend the service life of end equipment such as electric motors and generators, reducing equipment maintenance costs. Verified through testing, the product can withstand 5,000 stamping cycles without noticeable wear.
Electromagnetic Properties
Electromagnetic properties are the core advantage of Non-Oriented Electrical Steel. Zhongxin NOES perfectly meets the core requirements of low loss and high efficiency, helping customers enhance the market competitiveness of their end products and meeting high-frequency operating demands in high-end applications.
- The material has high magnetic permeability, effectively improving the energy conversion efficiency of electrical equipment.
- Extremely low iron loss significantly reduces energy consumption during equipment operation, achieving energy savings. Under the same operating conditions, energy consumption can be reduced by more than 30%.
- Stable magnetic induction intensity maintains excellent magnetic performance under different temperature and frequency conditions, ensuring stable operation of electric motors, generators, and other equipment.
Processability
Zhongxin non-oriented silicon steel possesses excellent processability, easily enabling various processing operations such as stamping, shearing, punching, and bending.
- The material surface is smooth and burr-free, reducing wear on processing dies and improving processing efficiency. Stamping speed can be increased by 25%, and die wear reduced by 30%.
- Supports high-precision processing: slitting tolerance up to ±0.01mm, stamping yield rate as high as 96%, edge cut squareness pass rate of 99.6% – no manual trimming required. Suitable for processing iron core components of various complex shapes.
- Whether for small-batch sample processing or large-scale production, stable processability is maintained, effectively reducing customer processing costs and shortening production cycles.

Non-Oriented Electrical Steel Factory and Supplier
Zhongxin Special Steel’s factory is located in Wuxi, Jiangsu Province, a core area with convenient transportation and advanced industrial development. The factory is equipped with standardized production workshops and advanced production equipment, achieving intelligent production across the entire process from raw material smelting, rolling, and annealing to final product inspection.
Production Process
NOES is produced using an advanced combination of “bell furnace + continuous furnace” processes. Every step – from raw material selection → smelting → hot rolling → cold rolling → annealing → surface coating → slitting → inspection → packaging – is supported by professional inspection equipment and strict quality control standards. An intelligent production system enables real-time monitoring and precise adjustment of process parameters, ensuring the steel has a uniform grain structure and stable magnetic properties.

A full-process quality inspection system is in place – from incoming raw material inspection and in-process inspection to comprehensive finished product testing before shipment – ensuring all performance indicators meet
customer requirements.
Packaging
Steel coil and sheet packaging strictly follows export standards. Moisture-proof and rust-proof materials are used, with the outer layer reinforced by steel strapping to effectively prevent loosening, rust, or deformation during transportation and storage.
