Bainitic grade SZBS800
Edition 06/2005
Usage
The thermo-mechanically rolled, microalloyed steel grade SZBS800 features a high tensile strength of ≥ 800 MPa with sufficient elongation for forming applications, such as rectangular tubes and profiles. Due to its chemical composition, it offers good weldability.

Chemical composition in percent by weight [%] (Heat analysis)
In addition, the elements Nb, V and Ti are each alloyed either individually or in combination (Nb + V + Ti ≤ 0,20 %).

Typical applications for making maximum use of the great tensile strength, at the same time as minimising the weight of the component, include mobile crane construction, longitudinal beams and cross members in trucks and trailers, safety components in passenger cars and wagon building.
