An excellent all-rounder

Hot-dip galvanized steel made by voestalpine is characterized by high corrosion resistance, high-quality appearance, excellent working properties and a wide spectrum of applications. The portfolio of steel grades ranges from super deep-drawing grades to grades with highest strengths (ahss advanced high-strength steels). Depending on customer requirements, voestalpine supplies a comprehensive range of available widths and thicknesses with tailor-made metallic coatings. A variety of surface finishing treatments also make it possible to extend the range of applications. voestalpine supplies high-strength steels with unique exposed-panel quality and offers a ZF coating for this purpose. The world's only hot-dip galvanized press-hardening steels made by voestalpine round off the extensive portfolio.

Materials for cold forming

Some steel grades are available as galvanized hot-rolled strip:

  • Hot-rolled low-alloyed or microalloyed steels
  • Hot-rolled ferritic-bainitic steels
  • Hot-rolled complex-phase steels

Materials for hot forming

Press-hardening steels for hot forming are available in various strengths and are coated with zinc or zinc-iron. Best crash behavior, high dimensional accuracy and very good joining properties are the hallmarks of components made of these materials.

Metallic coatings

Metallic coatings Z and ZM are available with normal (N) and small spangles (M). The surface of zinc-iron coating is spangle-free. Upon customer request, voestalpine supplies different zinc coatings per side (differential galvanizing).

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.
