Non-oriented semi-processed electrical steels Product Description
The semi-processed grades still need an additional annealing treatment step after the client's punching process. GNEE offers semi-processed standard grades and semi-processed high permeability grades. The overall average of polarisation in all directions of the high permeability steel sheet plane is therefore much higher than for the standard products.
Non-oriented semi-processed electrical steels Advantages
- Optimised punchability
- Controlled surface roughness
- Good material behaviour
- Reduction of losses and increased permeability of the steel.
The semi-processed high permeability grades allow core weight reduction and increased efficiency of motors and transformers. The improved efficiency achieved reduces machine operating costs and at the same time makes them more environmentally friendly.
Non-oriented semi-processed electrical steels Applications
- Non-alloyed semi-processed electrical steels are designed for small industrial motors, fans and domestic appliances such as washing machine motors, microwave oven transformers and refrigerator compressors
- Alloyed semi-processed electrical steels are designed for similar higher efficiency versions of these applications, as they have lower losses whilst the permeability remains at a good level
- Semi-processed high permeability grades are designed for motors, generators, transformers, converters and ballasts where higher efficiency is required
