Summary

The development of micro-alloyed high-strength steels at ThyssenKrupp Stahl started in the middle of the seventies. The metallurgical concepts were based on the micro-alloying elements titanium and niobium. The increased demands placed on the formability of high-strength steels, in particular of steels which are to be used for the construction of light-weight car bodies, call for both a higher tensile strength and an improved forming behaviour. Here, the focus is on a good stretch formability, since stretch forming is that forming strain to which car body closures are most frequently exposed. The high strength stretch forming steels (HSZ) developed at ThyssenKrupp Stahl meet this demand[1]. At the same time, these steels possess homogenous properties, even independent of the angle to the rolling direction.
