  • ArcelorMittal's wide range of electrical steels

ArcelorMittal's product range contains a very broad spectrum of steel grades with specific magnetic properties, including:

These magnetic materials are used in domestic appliances, building industry, mechanical engineering, electrical equipment, motors and generators including electric traction powertrains for automotive.

On top of this, ArcelorMittal offers a comprehensive range of services: technical support, R&D and steel service centres specialised in electrical steels.

 

iCARe® non-oriented fully processed range for automotive

Finding innovative (i) and environmentally friendly (e) solutions is essential for the CAR of tomorrow. These values form the core of the name iCARe®. Our iCARe® steels help automakers create environmentally friendly mobility solutions for a greener world.

Three steel types are included in the iCARe® offer

 

 

Non-oriented fully processed electrical steels

ArcelorMittal’s non-oriented fully processed electrical steels have guaranteed magnetic properties, in accordance with (or exceeding the levels required by) EN 10106:2015. As well as the maximum loss and minimum polarisation levels cited, full magnetic characterisation curves regarding losses, polarisation, permeability and apparent power at different frequencies are available on request.

Non-oriented semi-processed electrical steels

The semi-processed grades still need an additional annealing treatment step after the client’s punching process. ArcelorMittal 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.

Pole sheet electrical steels

Hot and cold rolled pole sheet grades are classified according to their yield strength (EN 10265:1995). As well as guaranteed mechanical properties, they have guaranteed magnetic properties, but unlike other electrical steel grades, their magnetic characterisation is determined under direct current (DC) conditions.

Grain-oriented electrical steels

ArcelorMittal’s grain oriented electrical steels (GO) are used in the cores of transformers which reduce or increase the voltage of an alternating current. Their superior magnetic properties and insulating coating significantly reduce electric power losses from the transformer.

Our grain-oriented electrical steels are supplied in the fully processed state and have guaranteed magnetic properties, in accordance with EN 10107:2014.

Cores

ArcelorMittal Technotron s.r.o. manufactures stacked, toroidal, cut, unicore cores and laminations (with cutting of 45 or 90°) from grain-oriented steel in thickness from 0.15 to 0.35 mm.

A world of varnishes for your applications

All our varnishes are environmentally friendly, hydrosoluble and chromium-free.

Each varnish for non-oriented grades (C3, C5, C6) has its own specific properties, such as insulation level, punchability effect, corrosion protection, temperature resistance and weldability. For grain-oriented grades, the C5-G type varnish provides increased surface insulation resistance.
