The cores of motors, transformers, and generators are made of electrical steel, also referred to as silicon steel, which is an iron and silicon steel alloy.
This more malleable kind of steel has a high permeability, little core loss, and a variety of magnetic characteristics. Its low magnetic hysteresis and iron losses, or energy loss, are caused by its tiny hysteresis curve. For electrical steel, there are two types of structures: oriented and non-oriented.
The structure of grain-oriented electrical steel allows for higher flux densities and magnetic saturation since the direction of the steel’s grains is constant and stable.
Grain-oriented electrical steel is most frequently used for transformers because they have predictable and precise magnetic field directions.
The Europe EV Steel Market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2026, registering a CAGR of XX% from 2022 to 2027.
At its Mardyck location in the north of France, ArcelorMittal has announced an investment with backing from the French government to build a new manufacturing unit for electrical steels. Direct jobs will be created by this investment.
All of the group’s electrical steels will be manufactured in France thanks to this new unit, which will focus on producing electrical steels for the engines of electric vehicles. It will complement ArcelorMittal’s current electrical steel factory at Saint-Chély d’Apcher, in the south of France.
These steels, which are used in engines as stacks of very thin layers ranging in thickness from 0.2 to 0.35 millimetres for the automotive industry, are distinguished by their magnetic and mechanical properties, including high polarisation to maximise engine performance, low losses to encourage vehicle autonomy, and high yield strength to support engine rotation.
