What is non oriented silicon steel?
Ferrosilicon alloy with very low carbon content. The grains in the deformed and annealed steel plate are randomly oriented. The silicon content of the alloy is 1.5% to 3.0%, or the sum of the silicon and aluminum content is 1.8% to 4.0%. The products are usually cold-rolled plates or strips with nominal thicknesses of 0.35 and 0.5mm, which are mainly used to manufacture electric motors and generators.

types of non oriented silicon steel
- Non-oriented fully processed silicon steel
Non-oriented, fully processed silicon steel has varying silicon levels that range from 0.5% to 3.25% Si. It has uniform magnetic properties in all directions. This type of silicon steel does not require recrystallisation processes to develop its properties. The low silicon alloy grades provide better magnetic permeability and thermal conductivity. For high alloy grades, better performance is expected in high frequencies, with very low losses. This type is excellent for magnetic circuits in motors, transformers, and electrical system housing. This fully processed type provides difficulty in punchability due to a completed annealing process. Organic coatings are added to improve lubrication in the punching process.
- Non-oriented semi-processed silicon steel
Non-oriented semi-processed silicon steels are largely non-silicon alloyed steel and are annealed at low temperatures after the final cold rolling. The end-user, however, has to provide the final stress-relief anneal according to the steel’s intended application. The punchability of this silicon steel type is better than the non-oriented fully processed type, so organic coatings are not required. Non-oriented semi-processed grades are good core materials for small rotors, stators, and small power transformers.
Non Oriented Silicon Steel Product Display
Cold Rolled Non Oriented Silicon Steel Classification
A. Silicon steel sheets can be divided into low silicon and high silicon according to their silicon content. Low silicon wafers contain less than 2.8% silicon. They have a certain mechanical strength and are mainly used to make motors, commonly known as motor silicon steel sheets. High silicon wafers contain 2.8%-4.8% silicon. They have good magnetism but are brittle and are mainly used for Used in manufacturing transformer cores, commonly known as transformer silicon steel sheets. There is no strict boundary between the two in actual use, and high-silicon wafers are commonly used to manufacture large motors.
B. According to the production and processing technology, it can be divided into two types: hot rolling and cold rolling. Cold rolling can be divided into two types: grain non oriented and grain oriented. Cold-rolled sheets have uniform thickness, good surface quality, and high magnetic properties. Therefore, with the development of industry, hot-rolled sheets have a tendency to be replaced by cold-rolled sheets (our country has clearly required the discontinuation of the use of hot-rolled silicon steel sheets, which is what was previously called "Cold instead of hot").

Non Oriented Silicon Steel Performance Index
A. Low iron loss. The most important indicator of quality, countries around the world use iron loss value to classify grades. The lower the iron loss, the higher the grade and the higher the quality.
B. High magnetic induction intensity. Silicon steel sheets can obtain higher magnetic induction under the same magnetic field. The size and weight of the motor or transformer core made with it are relatively small, which can save silicon steel sheets, copper wires and insulating materials.
C. The stacking coefficient is high. The surface of the silicon steel sheet is smooth, flat and uniform in thickness, and the stacking coefficient of the core is improved.
D. Good film processing properties. This is even more important for manufacturing small and micro motor cores.
E. The surface has good adhesion and weldability to the insulating film, and can prevent corrosion and improve punching properties.
F. Magnetic aging phenomenon is small. Silicon steel sheets must be delivered after annealing and pickling.
Properties of CRNO non oriented silicon steel
The addition of silicon in iron greatly improves the physical properties of electrical steels. Electrical steels have the following desirable properties for supporting the generation, distribution and consumption of electricity:
High permeability
increased capacity to support magnetic fields.
Low magnetostriction
low tendency to expand or contract in magnetic fields.
High electrical resistivity
lessens the core loss by reducing the eddy current component.
Decreased hysteresis loss
low hysteresis loss means less wasted energy in the form of heat from alternating magnetising force.

How to Maintain Non oriented Silicon Steel
Proper storage: When not in use, non oriented silicon steel should be stored in a dry environment to prevent rust and corrosion. Cover the steel with protective wraps or coatings to shield it from humidity and airborne contaminants.
Avoid mechanical damage: Handle silicon steel carefully to avoid bending, denting, or scratching the surface. Mechanical damage can impair the material's magnetic performance and increase electrical losses.
Insulation integrity: Regularly inspect the insulation on non oriented silicon steel laminations for any signs of wear, cracking, or peeling. Ensure that the insulation remains intact to maintain its effectiveness in preventing eddy current losses.
Environmental control: Monitor the operating environment to ensure it does not exceed the maximum temperature and humidity levels specified for the non oriented silicon steel. High temperatures can degrade the insulation and alter the magnetic properties.
Prevent corrosion: Apply rust inhibitors or coatings where necessary, especially if the silicon steel is exposed to corrosive environments. Regular cleaning with mild detergents can help remove corrosive substances that may adhere to the steel surface.
Monitor operating conditions: Keep track of the operating conditions of silicon steel in electrical equipment, such as in transformers or motors. Excessive heat, vibration, or mechanical stress can accelerate material degradation.
Periodic inspections: Perform regular inspections of the silicon steel components to identify any issues early on. Look for signs of deterioration, such as discoloration, warping, or delamination of the laminations.
Thermal management: Ensure adequate cooling is provided to the silicon steel in high-load applications. Implement heat sinks, fans, or liquid cooling systems if necessary to dissipate heat effectively.
Replace damaged components: If any part of the non oriented silicon steel exhibits signs of damage or deterioration, replace it promptly to prevent further degradation and ensure the reliability of the system.
Training personnel: Educate maintenance personnel about the proper handling and care of non oriented silicon steel to minimize the risk of damage during service and maintenance activities.
