Electrical steel strip

Electrical steel strip

isovac®, the non-grain-oriented electrical steel made by voestalpine, is characterized by best magnetic properties. Low core loss as well as high permeability and polarization make it possible to manufacture products with the highest energy efficiency. The homogeneity of the mechanical-technological properties and strip geometry across the entire surface ensure optimum and stable processability.

The homogeneity of the mechanical-technological properties and strip geometry across the entire surface ensure optimum and stable processability.

Applications

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).

Processability

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.

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. They have developed into 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.

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. Hot-rolled Q for the tube and section industry is a package full of quality and efficiency improvements for production as well as for the end product.
