Galvanized hot-forming steels for press-hardened components in 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.

Press-hardening steel, perfect for lightweight automotive design
Economical manufacturing
Simple process steps
Less material usage
Good crash performance (ductility)
Strengths of up to 1,500 MPa
Very good adhesive properties
Best paintability
Suitable for tailored-property parts
Standard corrosion protection for transports
The solution 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.
Experience phs-directform® in serial production
phs-directform® components are produced in series at the voestalpine plant in Schwäbisch Gmünd. We invite you to convince yourself of the technical and economic production advantages.
