voestalpine phs-directform®

Galvanized hot forming steels for the production of press-hardened components using the direct process

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.

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.
