phs-ultraform®

The revolution in automotive light-weight design.

phs-ultraform® stands for press-hardened steel components made of hot-dip galvanized steel strip produced by voestalpine. The phs-ultraform® product combines light-weight design, corrosion protection and increased automotive safety. phs-ultraform® is used in crash- and corrosion-resistant components such as automotive stiffeners, A and B pillars, sills, tunnels and bulkheads.

The benefits of phs-ultraform®

  • Corrosion protection: A special feature of phs-ultraform® components is their cathodic corrosion protection. This time-tested corrosion protection is now also available in press-hardened components.
  • High strength: phs-ultraform® is characterized by high strength up to a guaranteed value of 1,800 MPa.
  • Safety Press-hardened components significantly enhance vehicle passenger protection and substantially reduce the weight of the car body.
  • Complex components: phs-ultraform® offers the possibility of producing components with various strength and thickness combinations. Partial press-hardening allows the production of press-hardened components in precisely defined zones with differing strength.
  • Economy: Fuel consumption is reduced through light-weight phs-ultraform® design, and the CO­2 emissions are reduced. Even more weight reduction is possible through the use of mechanically tailored-property parts.

Indirect and direct hot-forming process

voestalpine is the only manufacturer to produce components made of phs-ultraform® in either the direct or indirect process. Depending on specific customer requirements, either the indirect or direct process may be the more economically efficient solution.

  • Indirect process: In indirect processing, blanks made of phs-ultraform® are formed and cut to final geometry using conventional cold-forming technologies. The cold-formed components are then heated to approximately 900 °C. In hot condition, the component is hardened and the geometry finalized through cooling in the press, the so-called form-hardening process. Press-hardening in the indirect process makes it possible for users to enjoy the highest freedom of design and highest dimensional accuracy. This is especially economical when producing high numbers of parts.
  • Direct process: Ultra-high-strength components with cathodic corrosion protection and highest dimensional accuracy can now be manufactured using the direct process. The phs-ultraform® blanks are heated to approximately 900 °C and press-hardened to final geometry in a single step. The direct process is optimal for smaller numbers of produced parts and for component geometries that are not too complex.
