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

  • Mild steels
  • Structural steels
  • Micro-alloyed steels
  • Bake-hardening steels
  • High-strength IF steels
  • Carbon-manganese steels
  • Dual-phase steels
  • Dual-phase high-ductility steels
  • Complex-phase steels
  • Complex-phase high-ductility steels

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

  • Zinc (Z) for applications subject to average corrosion (galvanized)
  • Zinc-iron (ZF) for corrosion protection with highest weldability requirements (galvannealed)
  • Zinc-magnesium (ZM) for best cathodic corrosion protection (corrender)

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).

"At the Linz site, we manufacture a very extensive product mix in five different hot-dip galvanizing lines. We apply zinc coatings in various surface qualities on mild to high-strength steel grades. Our team of specialists meets the challenge with a high level of commitment and quality awareness every single day. We set the standards with additional chromium-free and environmentally friendly treatments such as clearcover or multiface®.

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.
