Processing Forming Metallurgy Joining Feedback Form

New Advanced High-Strength steel (AHSS) grades are now available, which have significantly improved material properties (higher strength and ductility for cold stamping) compared to the steels of only a few years ago. These multi-phase materials have sufficiently different mechanical responses when subjected to actions in processing and forming. Tool part processing design, tool steel application, trimming and piercing, lubrication, and knowledge of local and global formability, must be considered for a robust serial stamping life cycle.

AISI has assembled information related to the use of AHSS in 4 topical categories. Within these categories are several opportunity statements that lead to training links.

To use this application, click on the topic of interest below and follow the links available to get to a listing of KEY knowledge needs and associate training options.

AISI has assembled these training links for quick access to support your needs and questions. We make no endorsements about the information gained from the links and are not responsible for the results of implementation.

Forming

Tool Wear

Stamping AHSS can lead to significant galling and tool wear requiring shorter maintenance intervals for polishing and of re-welding.

Edge Cracking

There can be edge cracking in AHSS forming without significant edge strain.

Drawing AHSS

Wrinkles, thinning & splits occuring where not predicted (Global Formability)

Press for AHSS

Tooling design and selection of parameters need to be considered for AHSS forming and trimming to avoid damage to equipment.

Springback with AHSS

Stamping AHSS leads to increased springback.
