The innovative bainitic, hot-rolled strip steels SZBS600 and SZBS800 belong to the group of multi-phase steels and are characterized by a unique microstructure architecture which results in a very homogeneous hardness distribution. This means fewer starting points for crack propagation than in conventional multi-phase steels.
- very high hole expansion ratio up to 75 %
- low edge crack sensitivity
- good fatigue properties
- high yield strength
SZBS600:
- Yield strength Rp0,2 (in MPa): 480 -580
- Tensile strength Rm (in MPa): 590 -670
- Elongation A80 (in %): ≥161
SZBS800:
- Yield strength Rp0,2 (in MPa): ≥680
- Tensile strength Rm (in MPa): 800-980
- Elongation A80 (in %): ≥101
1 to nominal thickness e ≥ 3mm applies A5.
