Theme1:Hot stamping of ultra-high strength steel parts

Overview

Hot stamping of quenchable steel sheets is a useful process for producing ultra-high strength steel parts. In the hot stamping processes, the forming load is small, the formability is high, and the springback hardly occurs. In addition, the stamped parts are hardened by die quenching, a tensile strength between 1.5 and 1.8 GPa.

Theme2:Plate forging

Keywords

Cold stamping, thickness distribution, thickening

Theme3:Joining by plastic deformation
