摘要：

This work proposed a simplified process to obtain high ductility of 2000 MPa press hardening steels (PHS) by smartly controlling auto-tempering. Without an additional tempering, a 2000 MPa PHS with remarkable combination of high strength, ductility and toughness was successfully produced by the novel industrial hot stamping process.
