Die materials and wear in stamping AHSS
Figure 1 Shown here are the five tool failure mechanisms and the changes recommended to prevent them. Editor's Note: This article is Part I of a three-part series that reviews the die materials and die coatings used in forming AHSS. Parts II and III, which will appear in future issues,...

AHSS stamping simulation: All things being (not) equal
Figure 1
While AHSS does present some major hurdles for stamping, simulation software has no insurmountable obstacles.
When people hear advanced high-strength steel, they think about entering new territory; about reconsidering traditional ways of designing a stamping operation; and... Read more...

Forming AHSS: Playing by new rules
The shop floor at MBtech Autodie in Grand Rapids, Mich., has more than 30 presses for die tryout. In recent years the company has made great strides building dies for AHSS. Mention a certain material is predicted to overtake mild steel as the auto sector's most popular material in 10 years,... Read more...

Advanced materials require advanced knowledge
Mode 1 failure (left) shows that separation occurs through the opposing sheet around the base of the weld, resulting in a full- button pull. In Figures 1-8, nugget size is nominally 6 mm in diameter. Mode 2 failure (middle), also known as a partial-thickness fracture and partial-button... Read more...

AHSS Tooling Requires Greater Protection
Just as the coating on M&M's® breaks under pressure, tool coatings have a tough time standing up to the extreme pressure of advanced high-strength steel (AHSS) forming. Because AHSS requires twice the energy force to form ( Figure 1 ) and the tooling has less wear resistance but... Read more...

Introduction to advanced high-strength steels - Part I
Editor's Note: A version of this article appeared in the November 2004 issue of STAMPING Journal® .
Several new commercialized and near-commercialized advanced high-strength steels (AHSS) that exhibit high strength and enhanced formability are being offered around the world. These steels... Read more...
