In order to be able to compete with other lightweight materials over and over again new steel grades are developed.
In the cold bent part the property distribution of material is almost homogeneous, in the laser assisted bent part the property distribution of the material are inhomogenous.
During the cold forming the material in the forming zone is hardening and thus material from the not deformed zone flows into the bending zone.
