Abstract
A blank cut from a strip of hardenable hot-formed steel is heated in a furnace to a temperature which is smaller than an Actransformation point in an iron carbon diagram. A first region of the blank is then heated in a conductive heating station to a temperature above the Actransformation point and subsequently hardened in a hot forming and hardening tool to produce a steel part with at least two microstructured regions of different ductility.
