SZBS800®+Z

The innovative bainitic hot-rolled strip steel is a multiphase steel with a unique microstructure for a very uniform hardness distribution. This results in a material that is less susceptible to cracking than conventional multiphase steels. The material features a very high yield strength and tensile strength with sufficiently high elongation at break for cold forming processes. If offers the following positive characteristics:

• In the xpand^® variant, with increased hole expansion ratio and the associated low edge crack sensitivity
• Process-reliable manufacturing of very complex component geometries with high strength
• Great potential for component integration
• Good fatigue properties particularly under dynamic stresses
• Light-weight construction potential due to reduced sheet thicknesses and a design better suited to the component
• Very good weldability

The hot-dipped zinc coating and StronSal^® (zinc-magnesium) coating offer two alternatives for corrosion protection.

Grade SZBS800+Z material is used in both the body and the chassis.

In the vehicle body, the material is particularly used in elements relevant to safety, such as reinforcements and supporting structures.
