| 摘要 |
<p>This invention pertains to a process for producing shaped components from high-strength and ultra high-strength steels with tensile strengths > 780 MPa, wherein a steel sheet-metal strip 2 is fed to a roll-forming installation and in the roll-forming installation is passed through roll stands (11, 12) and deformed by means of deformation rollers acting on the steel sheet, and wherein to avoid hydrogen embrittlement in plastically deformed regions of the deformed steel sheet-metal strip compressive stresses are introduced by stamping and/or upset-forging and/or bending and/or overbending and bending-back or by machining the strip edges.</p> |
