Electrical steel, also known as silicon steel, is a special steel tailored to achieve specific magnetic properties. It is used for high-end applications, such as e-vehicle or windmill motors, energy generators or power transformers, but its high silicon content makes it extremely sensitive to manufacturing.

NON-GRAIN ORIENTED STEEL
Non-grain oriented (NGO) steel with high-efficiency magnetic properties and low iron loss involves a combination of process:
- Annealing & Pickling Line (APL)
- Cold Rolling Mill (CRM)
- Annealing & Coating Line (ACL)
Fives' technology achieving record performances:
- Strip temperature: up to 1,100 °C
- Process speed: 200 mpm
- H2 atmosphere: up to 100%
- 0.1 mm rolling thickness on full width
GRAIN ORIENTED STEEL
The production of grain oriented (GO) steel has an extremely high capital cost per tonne and requires complex manufacturing and technology:
- Annealing & Pickling Line (APL)
- Cold Rolling Mill (CRM)
- Decarburizing & Coating Line (DCL)
- Flattening & Coating Line (FCL)
Fives' technology achieving record performances:
- Strip temperature: up to 1,100 °C
- Process speed: 160 mpm
- H2 atmosphere: up to 75%
