HEAT – THE KEY TO HIGHEST STRENGTHS
When aiming to achieve such high strengths, the selection of available steels limits itself to those of such qualities that enable it to develop its properties once a specific heat treatment has been applied.
This is precisely the group of steels that press hardening addresses. Here, the key feature is that embedding the shaping in to the temperature-time cycle of hardening not only achieves the highest strengths, but enables exceedingly complex component geometries with comparably low forming forces to be set in one processing step.
The passenger compartment of the Passat built in series with press-hardened components starting in 2004 represents a never before achieved lightweight construction dimension coupled with the highest level of safety.
