voestalpine phs-directform®

The pioneer in galvanized, press-hardened components produced through direct forming

The world novelty developed by voestalpine is directly hot-formed, hot-dip galvanized steel strip to be used in corrosion-resistant light-weight components for the automotive industry.

phs-directform® is the technically simple, safe solution for complex components and high efficiency, even in small quantities. The material is suitable for forming in existing and adapted direct-hot-forming lines. phs-directform® boasts of excellent strength, is suitable for joining, and its excellent corrosion protection make it recommendable for structure and body crash components.

  • Strengths ranging from 1,500 to 2,000 MPa
  • Very good processability and coatability
  • Suitable for tailored-property parts
  • Standard transport corrosion protection

The innovation for complex components made of press hardened steel

The blanks are heated to roughly 900 °C. This is followed by an innovative non-contact pre-cooling process that uses air to cool below 550 °C in an effort to prevent microcracks. During the subsequent forming process, the blanks are brought to their final geometry and hardened. Tailored-property parts can also be manufactured from laser-welded blanks.
