Steels 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®)

corrender® is the high-performance zinc-magnesium-aluminum coating made by voestalpine.

The corrender® surface achieves a significantly higher corrosion resistance than conventional galvanized steel strip, despite its reduced layer thickness. The surface is characterized by excellent forming properties, minimized friction and efficient postprocessing.
