Looking for the lightweight automotive design of tomorrow?

The automotive industry is undergoing unprecedented change. Technological developments are progressing at an enormous pace. The demands on efficiency and safety are enormous and are being completely redefined in ever shorter periods of time. In this highly innovative environment, anyone who believes that today's solutions must be valid tomorrow will be proven wrong by the competition. voestalpine is working now on the solutions of tomorrow. Whether for crash components, exposed panels that meet the highest surface requirements or body-in-white components, voestalpine provides the best solution for every demand of the automotive and automotive supplier industries. That is why leading OEMs and automotive component suppliers place their trust in voestalpine.

Let your ideas fly! That's ultralights

Transforming ideas into lighter, stronger and more corrosion-resistant components. That is the credo of ultralights made by voestalpine. The ultralights made by voestalpine offer a comprehensive range of steels for lightweight automotive design, from advanced high-strength steels (ahss) for cold forming to innovative solutions for the hot forming of galvanized press-hardening steels (phs). That is how voestalpine pushes the limits of what is efficiently feasible in the automotive industry.

Lightweight AND crash-safe!

Weight reduction is a central objective in the automotive industry. Less weight results in advantages in performance and efficiency. But does reduced weight also mean less stability? Results from the voestalpine crash simulator prove otherwise. This is where the high-strength and innovative car body steels of voestalpine are tested to the limit so they can be used in demanding applications, even in the most extreme cases. The results speak for themselves. The progressive buckling behavior and energy absorption values are excellent in spite of the light weight of the material.

Who's Stella?

Stella Sustainable is a testimonial to the sustainable future of the automotive industry. Holistic corporate social responsibility (CSR) is of particular importance to voestalpine. There are many other issues in addition to climate protection, future steel production, ecological logistics and transparent supply chains. Because we care. Stella stands for a vision of the future in which mobility and the environment do not contradict each other.

Ready for a new Xperience?

The ahss high-ductility, complex-phase steel CP1400HD made by voestalpine redefines the limits of what is feasible in lightweight automotive design. Impressive formability and light weight in a strength class of 1400 MPa. The next level of cold forming.

Electrical steel for the drive

In addition to lightweight design and safety, the need for highly efficient electrical steel for rotors and stators in the drive train is becoming increasingly important in electromobility. There are already more than 100 electric motors installed in conventional cars. New drive motors present the industry with completely new challenges. isovac® is the electrical steel made by voestalpine and meets the challenges of highest energy efficiency.

corrender is convincing throughout the entire car body, even in exposed panels.

The performance of corrender can be applied throughout the entire car body. corrender optimizes every structural or internal component, including those that are forming-critical or highly corrosive. The potential savings in the corrender metallic surface coating offers greater corrosion protection when compared with classic galvanized steel strip.

Electrical steel strip

isovac® is the non-grain-oriented electrical steel made by voestalpine and stands for highest energy efficiency. Electrical steel is a material used in many different forms in the construction of magnetic cores in electrical appliances and machinery. voestalpine is Europe's market leader for non-grain-oriented semi-finished electrical steel.


isovac® made by voestalpine is a high-quality electrical steel for electric motors, generators and transformers of all kinds. 

The high demands of motors in general and especially drive motors in the field of e-mobility are met by isovac® with respect to efficiency and performance, highest permeabilities, lowest losses and, where required, high strength. 

Together with the pole plates of voestalpine, isovac® electrical steel makes a significant contribution in generator design with respect to increases in the efficiency of a wide range of generator types and sets new standards in terms of performance and sustainability.

The specialists of voestalpine are continually developing and optimizing special high-quality isovac® grades for static machines such as transformers, reactance coils or magnets for particle accelerators.

Product portfolio

Customized solutions are indispensable in a dynamic market marked by a wide variety of individual demands. With respect to compact engine design and high efficiency, voestalpine has just the right product for each customer.

Insulating varnish systems

The insulating varnish applied to the strip surface is a key factor in the highest performance of machines made of isovac® electrical steel. This is why voestalpine also relies on the highest quality of the insulating varnish systems. In close collaboration with leading European varnish manufacturers, voestalpine supplies insulating varnishes that contain no toxins, carcinogens, mutagens, formaldehyde or chromium compounds. The coatings meet all applicable EC directives (RoHS Directive 2011/65/EC).


Consistent mechanical properties across the entire length of the strip and clean surfaces that cause minimal abrasion on the punching tool are prerequisites to optimized punching processes.

The result of our stable and continuous rolling process is a reduction in the steel strip thickness tolerance value. Subsequent continuous annealing reduces material stress to a minimum. This enables voestalpine customers to manufacture components with the highest precision.

Mild, unalloyed steels for cold forming

These steels are generally delivered in accordance with EN 10111. They are used in applications in which formability is more important than strength.

Structural steels

These steels are included in EN 10025. One of their fields of application is in machinery. The steels are characterized by minimum yield strength, a margin for tensile strength and minimum fracture elongation. They are used for light drawing stress, forming and bending.

alform® steels

alform® is a brand name in the voestalpine Steel Division and stands for hot-rolled fine-grained steel with best cold-forming properties and excellent weldability. alform® steels are available in various grades and strength classes. Whether thermomechanically or normalized rolled, as hot-rolled strip or heavy plate, in coils, slit strip or cut sheets, alform® is an indispensable material in mechanical engineering, automotive design and in the processing Industry.

durostat® steels

durostat® grades are wear-resistant steels that feature high hardness achieved through accelerated cooling directly from the rolling heat. They are characterized by a high degree of wear resistance and are especially suited to applications with high mechanical stress and high levels of abrasion.

Case-hardening and heat-treatable steels

Case-hardening and heat-treatable steels pursuant to DIN EN ISO 683-1 and EN 10084 as well as the voestalpine standard are implemented in direct-processing applications or are used for cold re-rolling. These steels generally undergo heat treatment in order to achieve the desired processing and component properties. They are used in applications that must strike an optimum balance between hardness and toughness.

Pole sheets

Pole sheets are thermomechanically rolled steels with guaranteed magnetic properties. Standard grades are pursuant to Euronorm EN 10265:1995 (corresponding to IEC 404-8-5). Ultra-high-strength special voestalpine grades are also supplied.

Hot-rolled enamelable steels

The narrowest tolerances, high material quality and highly specialized application expertise guarantee products that meet every requirement. Combinations of thick hot-rolled steels and thin cold-rolled steels, for example, are often used in industrial silo designs.

Hot-rolled strip next level

We go one step further with hot-rolled Q for the tube and section industry. Q for even more quality than you would expect as a customer. Q for even more hot-rolled strip grades, especially in the tube and section industry. Characteristics that can all be of great importance to customers or just individually.
