Multi-phase steels are complex to cut and form, requiring specific tooling materials. The tooling alloys which have been used for decades, such as D2, A2 or S7, are reaching their load limits and often result in unacceptable tool life. The mechanical properties of the sheet steels achieve tensile strengths of up to 1800 MPa with elongations of up to 40%.  Additionally, the tooling alloys are stressed by the work hardening of the material during processing.

The challenge to process AHSS quickly and economically makes it necessary for suppliers to manufacture tooling with an optimal tool steel selection. This month’s AHSS Insights blog features a case study, contributed by Dennis McPike of Zapp Tooling Alloys, Inc.,  illustrates the tooling challenges caused by AHSS and the importance of proper tool steel selection.
