Innovative bainitic steel grades for the most demanding chassis components

General:

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.


Highlights:

Function enhancement


Customer benefits:

  • very high hole expansion ratio up to 75 %
  • low edge crack sensitivity
  • good fatigue properties
  • high yield strength

Characteristics:

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.
