Understanding the difference between grain oriented silicon steel and non grain oriented silicon steel is crucial for various industries. GOSS offers superior magnetic efficiency for transformers, while NGOSS provides uniform magnetic properties for electric motors and generators. Reading this blog will help you grasp the unique characteristics of each type and their diverse applications.
Grain oriented silicon steel, also known as GOSS, is a kind of electrical steel that is designed to have particular magnetic properties. It usually contains around 3% silicon, which appreciably increases its electric resistivity and reduces iron loss because of eddy currents.
Non-grain oriented silicon steel, often abbreviated as NGO or NGOSS, is a special type of electrical steel with specific magnetic properties. It is primarily comprised of silicon, ranging from 0.5% to 3%.
The manufacturing of grain oriented silicon steel is a complicated procedure that pursues to beautify the magnetic properties of metal by aligning its grain structure inside the course of the magnetic area.
Compared with grain oriented silicon steel, The production of non grain oriented silicon steel is much easier. It focuses on achieving uniform magnetic properties in all directions.
It is important to distinguish the magnetic properties between grain oriented silicon steel and non grain oriented silicon steel. Those differences notably affect their projects and overall performance in numerous electrical devices.
GOSS is characterized by its top-notch magnetic properties inside the course of rolling. This is because its grain shape is aligned at some stage in manufacturing, which helps less complicated magnetization in a specific route. Instead, NGOSS is famous for its isotropic magnetic properties, which means its magnetic characteristics are uniform in all instructions, normally weaker than in GOSS.
The magnetic flux density is a vital parameter in evaluating the performance of silicon steels in electrical applications.
GOSS typically presents better magnetic flux density along its rolling course in comparison to NGOSS. That is quantifiable in terms of higher induction at the identical magnetizing pressure.
| Types of Silicon Steel | Normal Magnetic Flux Density (T) |
| Grain Oriented Silicon Steel | 1.9 – 2.0 |
| Non-grain oriented Silicon Steel | 1.5 – 1.8 |
Core losses, which encompass hysteresis and eddy current losses, are another fundamental item.
Usually, GOSS shows lower core losses as compared to NGOSS because of its orientated grains, which reduce hysteresis losses via facilitating smoother area wall actions and decreasing eddy currents due to high resistivity. This discount is especially massive at high frequencies and flux densities.
| Types Silicon Steel | Core Loss at 1.5T, 50Hz (W/kg) |
| Grain Oriented Silicon Steel | 0.9 – 1.1 |
| Non-grain Oriented Silicon Steel | 1.6 – 1.9 |
The permeability of GOSS is appreciably higher along its grain orientation, enhancing its effectiveness in applications requiring excessive magnetic permeability which includes transformers and big generators. NGOSS, with its isotropic properties, is greater applicable for applications wherein uniform magnetic performance in all instructions is wanted.
The evaluation of electrical resistance between grain oriented silicon steel (GOSS) and non-grain oriented silicon steel (NGOSS) is important for knowing their suitability in specific electric applications.
The association of the grain structure in GOSS ends in lower electrical resistance within the route of the grain orientation, which complements the performance of electrical transformers wherein it’s far predominantly used. This lower resistance is superb in decreasing energy loss, which is essential in excessive-efficiency transformers.
However, non-grain oriented silicon steel does not have a fixed directional grain shape, which leads to an extra uniform electrical resistance in comparison to GOSS. Even as this may mean a slightly better resistance in general compared to grain oriented type, NGOSS gives flexibility in applications in which the magnetic subject route varies or is multidirectional, which includes electric automobiles and turbines.
GOSS is predominantly utilized in applications where high magnetic efficiency is crucial. Due to its top-notch magnetic properties, GOSS is more employed in the cores of transformers, especially in the ones designed for strength and distribution functions.
| Type of Transformer | utilization of GOSS |
| Energy Transformers | Used as the core to improve efficiency and decrease power losses at excessive power ranges. |
| Distribution Transformers | Applied to beautify magnetic properties which is crucial for the green distribution of energy in residential and business areas. |
Apart from transformers, GOSS is also hired in the manufacture of high-performance inductors and reactors used in switch-mode strength elements (SMPS). These gadgets perform at excessive frequencies, and the residences of GOSS help minimize core losses, which is crucial for maintaining performance and reliability in these applications.
In comparison, NGOSS is substantially used in numerous applications wherein uniform magnetic properties are required in all guidelines. It usually includes electric-powered motors, energy mills, ballasts, compressors, electromagnetic valves, welding machines, and so on.
Influenced by their production complexity and market demands, the cost of grain oriented steel and non-grain oriented silicon steel vary appreciably. Knowing those variations is essential for stakeholders in industries that include electric engineering and electronics manufacturing.
The production of GOSS involves a greater complex and controlled method than NGOSS. This includes the particular orientation of grains, which not only enhances their magnetic properties but also adds to the manufacturing value. Therefore, GOSS is normally more costly than NGOSS. The precise cost difference can vary depending on the grade of silicon steel and the quantity of manufacturing.
| Silicon Steel | Common Cost |
| Grain Oriented Silicon Steel | 20-30% higher than NGOSS |
| Non-grain Oriented Silicon Steel | Base fee |
Market availability of both kinds is stimulated through worldwide needs and production regions.
GOSS, with its specialized usage in transformers and large electric-powered motors, tends to have a greater niche marketplace. This specialized call frequently results in much less fluctuation in its marketplace availability as compared to NGOSS, which is widely used in various electric and motor applications. The wider application range of NGOSS is usually greater available on the worldwide marketplace.
Both types of silicon steel are in general produced in areas with strong steel production talents along with China, Japan, and Europe. However, shifts in market dynamics, along with improvements in opportunity materials or changes in strength guidelines, can impact the provision and call for both GOSS and NGOSS.
| Silicon Steel | major Production Areas | Primary Applications | Marketplace Fluctuation |
| Grain Oriented Silicon Steel | China, Japan, Europe | Transformers, high-efficiency vehicles | Stable, niche |
| Non-grain Oriented Silicon steel | China, Japan, Europe | general electric powered cars, automotive parts | Variable, extensive |
In conclusion, both GOSS and NGOSS are two main types of electrical steel used in electrical engineering. But as variants, they have many differences in terms of production, magnetic properties, applications, cost, and market availability.
