S-in motion key figures and impact

S-in motion project roll-out in 2011-2012 • Catalogue of solutions for weight/cost savings:

– Up to 20% weight savings

– Reduction in Green House Gas (GHG) emissions during the phase of the whole vehicle => -6.2 g CO2 / km

• 31 customer events held in Europe, Asia, North America and South America at main car makers and Tier 1 suppliers

– 8,500 registered visitors (275 on average per event, incl. top management, purchasing, design engineers etc)

• Events at major European truck makers scheduled for 2013

3 main impacts on market• Increased collaboration with OEMs

on co-engineering activities

• Contribution to significant growth of Advanced High Strength Steels in the car industry

• Increase of our patented solutions (e.g. Usibor® and Laser Welded Blanks)

A quote from Volkswagen

“Volkswagen is using high strength steels in increasing amounts. It is a very cost effective way of reducing weight. Using new innovations in steel engineering… it is possible to reduce weight without the use for more costly materials such as aluminium and carbon fibre.”

Armin Plath, VW’s Head of Materials Research and Manufacturing

New electrical steels for new electric motor demands

• Launched in June 2012, iCARe™ is ArcelorMittal’s new range of innovative (i) and environmentally friendly (e) electrical steels for the CAR of tomorrow.

• 3 main steel types:• Save: for very low losses, extending

the car’s range• Torque: for the highest levels of

mechanical power output, boosting acceleration

• Speed: high strength electrical steels for high speed rotors, increasing performance at high speeds

• This iCARe™ offer is supported by €90 million investment on the annealing line in St. Chély d’Apcher (France)

• Volume capacity: 120 kt/year, expandable to 250 kt/year to meet future demand

• Start production of new line: May 2013
