Product Portfolio

Widest Steel Product Portfolio for Automotive

ArcelorMittal’s automotive steel product portfolio is the most extensive in the industry. Automakers that work with us are part of the story behind our steel products and solutions.

Over two-thirds of a car is typically made of steel. Whatever part or vehicle automakers and their suppliers are building, ArcelorMittal works alongside them to design and deliver cutting-edge, lightweight, efficient, safe and easy to implement steel solutions. These deeply engrained partnerships with our clients, paired with the industry’s largest R&D team in North America, contribute to an extensive and unmatched automotive product portfolio.

And it’s not just the quantity of product, it’s the quality. For example, while most auto standards require 1200 MPa tensile strength in Multi Phase Grades, ArcelorMittal has achieved 1500 MPa, while also delivering on customer requirements for formidability and flatness.

Our Press Hardenable Steels (PHS) are ultra-high strength steels that can be formed into complex shapes, ideal for hot stamping process. They can be used separately to form monolithic parts or together into a single laser-welded blank offering weight savings, improved crash behaviors and cost savings through material and manufacturing optimization. PHS steels include Usibor^(R) for critical parts when strength is key, and Ductibor^(R) for optimized ductility and strength.

Our Hot Roll Grades are perfect for pick-up truck frames and chassis parts that are increasingly requiring higher strength in heavier battery electric and hybrid powertrains. Our HR780 and 980 steels are designed for higher strength and durability in frames.

Rounding out the products, our Exposed Steel Grades offer a combination of excellent formability and surface appearance. Ultragal^(R) features a Zinc-based coating with superior surface appearance, while Zagnelis^(R) offers far superior corrosion protection compared to traditional Zinc-based coatings.

Our 3^rd Generation Cold-Stamped Steel Grades high strength steels can be formed into complex shapes with cold stamping process and they offer weight savings, improved crash behaviors and cost savings through material optimization. Fortiform^(R) 980 and 1180 offer high formability for complex parts that require strength and energy absorption.

BEVs

Forging Electric Automotive Partnerships

This part of our steel story is constantly in motion and always in the fastlane. We’re constantly examining how steel can contribute to the design, safety and function of today’s latest vehicles as well as the vehicles of tomorrow.

By working closely in collaboration with automakers, ArcelorMittal is answering the challenges presented by the emergence of global automotive trends such as electric, connected and self-driving vehicles.

ArcelorMittal’s range of advanced high-strength steels (AHSS) can be deployed to meet the weight, safety, sustainability, cost, and performance targets of BEV producers. Our S-in motion® BEV study shows how these smart steels and steel solutions can be applied to three key parts of BEVs: the battery pack, the body-in-white (BIW), and chassis components.

In addition, ArcelorMittal's iCARe® range of electrical steels was designed specifically for e-traction systems that power electric vehicles. We put the right steel in the right place using best-in-class solutions. By doing this, we are not only contributing to BEVs, but optimizing their performance.

An increasing number of automakers are shifting gears from an aluminum-intensive battery box to our Multi-Phase steel​ solution. A steel battery enclosure offers unequivocal strength and protection for battery enclosure, with advanced energy absorption in the event of a crash.

Multi Part Integration

Harness the strength of steel and the power of less

In a rapidly evolving automotive industry, flexibility wins. That’s why ArcelorMittal’s Multi Part Integration™ (MPI) process is becoming an increasingly bigger part of our story. Our automotive partners benefit from the power of less - less parts, less process, less floor space, less time, less materials, less CO₂ and less assembly cost.

ArcelorMittal’s Multi Part Integration™ (MPI) process is becoming an increasingly bigger part of our story. Our automotive partners benefit from a more efficient, sustainable and simplified manufacturing process.

The MPI concept allows multiple vehicle components to be integrated into one by using the latest press hardenable steels (PHS). MPI is one of the most cost-effective ways for automakers to develop and deploy sustainable mobility solutions while simplifying vehicle design and production. It’s a game-changing solution and a proven alternative to die cast aluminum or aluminum gigacasting.​

Both Laser Welded Blank (LWB) technology and Tailored Blanks - including ultra-high strength cold stamping steels and Usibor^® and Ductibor^® hot stamping steels - allow significant reductions in costs, weight, emissions, and lower investments in tools and production space. It is a radical simplification of the vehicle production process that offers crash optimization, considerable sustainability gains and cost savings for automakers of up to 10 percent.

ArcelorMittal is undertaking further studies to continue to develop the MPI concept in response to new challenges facing the automotive market.
