Bainitic grade SZBS600

General Information

The thermo-mechanically rolled, micro-alloyed steel grade SZBS600 features a high tensile strength of 590 MPa with sufficient elongation for forming applications, such as rectangular tubes and profiles. Due to its chemical composition, it offers good weldability. This steel grade is not standardized and it is classified in strength class D.

Application examples

Thanks to the combination of high yield strength and high fracture elongation, the SZBS600 is appropriate to chassis parts with complex geometry, for example transverse links.
