Grain Oriented Electrical Steel (GOES) is a highly specialised steel designed for maximum magnetic performance in transformers and high-efficiency electrical equipment. Its carefully controlled grain structure allows magnetic flux to travel with minimal energy loss, making it essential for modern power generation and distribution systems. At Stephens Gaskets, we supply high-quality grain oriented electrical steel sheet and strip material to manufacturers who require reliability, precision, and consistent magnetic performance.
With over 70 years of experience supplying sheeting and strip materials alongside gaskets, shims, and washers, we understand how material quality directly affects operational efficiency and long-term durability.
What Is Grain Oriented Electrical Steel?
Grain oriented electrical steel is a silicon alloy steel engineered so that its crystalline grain structure is aligned in the rolling direction. This alignment significantly improves magnetic permeability while reducing core losses.
GOES is typically supplied in laminated sheet or strip form and is used as the core material in transformers and certain types of generators. The orientation of the grain structure ensures optimal magnetic flow in one direction, which is critical in transformer core design.
Why Grain Orientation Matters
In conventional steel, magnetic properties are relatively uniform in all directions. In grain oriented electrical steel, the rolling and annealing processes create a directional grain structure that enhances magnetic performance along the rolling axis.
This results in:
- Lower core energy losses.
- Improved magnetic permeability.
- Higher efficiency transformer cores.
- Reduced heat generation.
- More compact and cost-effective designs.
For manufacturers of power equipment, these performance gains translate directly into improved efficiency and compliance with energy regulations.
Key Benefits of Grain Oriented Electrical Steel Sheet
1. Energy Efficiency
GOES typically contains around 3% silicon, which enhances electrical resistivity and reduces eddy current losses. This makes it ideal for energy-efficient transformer production and high-performance generator applications.
2. High Magnetic Performance
The controlled grain growth during production results in superior magnetic properties in the rolling direction. This ensures reliable performance in demanding electrical environments.
3. Reduced Maintenance and Operating Costs
By minimising energy loss and heat generation, grain oriented electrical steel helps extend equipment lifespan and reduce ongoing maintenance requirements.
4. Consistent Manufacturing Quality
At Stephens Gaskets, we supply grain oriented electrical steel sheet that meets strict quality standards, ensuring consistency across batches and dependable material performance.
What Is Grain Oriented Electrical Steel Used For?
Grain oriented electrical steel is primarily used in:
- Power and distribution transformers.
- High-performance electrical generators.
- Industrial energy systems.
- Specialist electromagnetic equipment.
In transformer cores, laminated GOES sheets are stacked to reduce eddy currents and optimise magnetic efficiency. This enables seamless, reliable operation under continuous load.

FAQs
1. What is grain oriented electrical steel used for?
Grain oriented electrical steel is primarily used in transformer cores and high-efficiency electrical generators where reduced energy loss and high magnetic permeability are essential.
2. Why is silicon added to grain oriented electrical steel?
Silicon increases electrical resistivity and reduces eddy current losses, improving overall energy efficiency in transformer applications.
3. What is the difference between grain oriented and non grain oriented electrical steel?
Grain oriented electrical steel has a directional grain structure optimised for magnetic flow in one direction, whereas non grain oriented steel provides more uniform magnetic properties in multiple directions.
