1310MPa-Class Bumper Beam — Into the Strength Range Where Stamping Cracks
1310MPa-class steel — beyond cold stamping's comfort zone — mass-produced via progressive roll-form bending, with closed sections for crash performance.
- 01
Challenge
A bumper beam is the first part to absorb crash energy, and its strength class keeps climbing. At 1310MPa, cold stamping shows severe cracking and springback, while hot stamping carries heavy equipment and energy costs.
- 02
Approach
Progressive roll-form bending shapes 1310MPa steel cold, and spot welding closes the section. The partner factory — with a library of roughly 100 section profiles — proposes energy-absorbing section designs from the drawing stage.
- 03
Outcome
In mass production as bumper reinforcements for automotive customers — meeting crash requirements with far less equipment burden than hot stamping.
