In the context of lightweight vehicles, tailored properties high-strength steel parts play a vital role in improving safety under car collisions. Hot stamping technology provides good formability for manufacturing high-strength steel parts with tailored properties, and the hot stamping parts have high strength, small springback and good industrial promotion prospect. This paper summarizes the current state-of-the-art processes for the implementation of hot stamped parts with tailored properties, through intrinsic strategy and tailored welded / rolled blanks.
