- Abstract
- Press hardening steel (PHS) is increasingly being used for the manufacture of structural automotive parts. One of the most critical characteristics of PHS is a low residual ductility related to its martensitic microstructure. Recently, the application of quenching and partitioning (Q&P) processing to PHS has been shown to result in a significant improvement of the mechanical properties [1]. The present work focused on the use of Q&P processing to improve the ductility of PHS. The effect of the partitioning time on the microstructure and mechanical properties of a Q&P processed 30MnSiCrB6 PHS was analyzed. The Q&P processed 30MnSiCrB6 PHS contained a high volume fraction of C-enriched retained austenite, and excellent mechanical properties as compared to the standard 22MnB5 PHS grade. The considerable improvement of both the ductility and the bendability of the Q&P-compatible PHS should lead to an improved in-service ductility beneficial to passive vehicle safety.
