Advanced High Strength Steels (AHSS) and High Strength Steels (HSS) have become the dominant material choice for lightweight construction in the automotive and transport sector for being affordable, easily manufactured and recycled.
As new grades of high-strength steels are developed, more limitations in cracking resistance and formability appear during their processing, which may trigger edge-cracking problems, shear affections such as cut-outs in inner panels or corners, hub holes or hidden joints that compromise part quality.
