Publication number: 20090151821Abstract: Compared to conventional steel products, polyphase steels have a significantly improved combination of resistance and ductility and are therefore becoming more and more important—especially for the automobile industry. The currently most important steel groups for the automobile industry are dual phase steels and TRIP steels. The production of different polyphase steel resistance categories, carried out directly on a hot strip, for meeting various requirements, requires a highly extensive know-how and firstly a corresponding adaptation of the alloy elements. According to the invention, a heat treatment (30) with a variable heating temperature and heating duration is carried out following the actual production of polyphase steels with a standard analysis and a standard process execution, whereby almost any combination of different materials or combination of properties (height of yield stress, level of tensile strength) can be adjusted.Type: ApplicationFiled: December 11, 2006Publication date: June 18, 2009Inventors: Christian Bilgen, Wolfgang Henning, Ingo Schuster
