Advanced Stamping Materials

1-Day Course

The objective of this course is to provide an understanding of the applications, benefits and guidelines for Advanced Stamping Materials. It will include Advanced High Strength Steels (AHSS), Dual Phase and Trip steels. Recommendations for part design with respect to issues related to die maintenance, manufacturing, and welding will be provided.
