Bainitic grade SZBS800

Usage

The steel grade SZBS800 features a high tensile strength of ≥ 800 MPa with sufficient elongation for forming applications. Due to its chemical composition, it offers good weldability.

Application examples

Typical applications for making maximum use of the great tensile strength, at the same time as minimizing 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.
