Stamping and die designers are interested in the forming capabilities of the steels they specify. Complex stampings are created from several different basic forming modes, which are sensitive to different mechanical properties. For this reason, steel formability, especially for AHSS grades, cannot be characterized by a single number, but instead must be done for each basic forming mode.sp.info AHSS Stamping - Auto/Steel PartnershipThe Stamping Team has multiple projects addressing springback including; Modeling, Combination Bead Die, Hybrid Bead and Twist Die Studies. 3rd Gen AHSS Press Tonnage.

All deformation occurs at a radius, so there is no sidewall curl risk and overbending works to control angular springback.See all results for this question
Third-generation AHSS offers the vision of producing some of these B-pillars through cold stamping. OEMs, Tier Ones and other stampers will conduct business-case investigations to determine the most effective approach, which may be volume-sensitive. Hot stamping requires a large capital investment, more energy and more-expensive dies.See all results for this questionsp.info How is hot stamping used to make steel?In its simplest definition, hot stamping, also called hot forming or press hardening, is the process of forming metal while it is very hot (in excess of 900 degrees C) and then quenching it (cooling it quickly) in the die. The process converts low-tensile-strength metal to a very high-strength steel (150 to 200 kilopounds per square inch (KSI). 2.See all results for this questionsp.info Forming AHSS: Playing by new rules - The FabricatorJul 15, 2008 · The varieties of AHSS do exhibit high formability, but in entirely different ways from legacy materials. According to sources, it's more than just high amounts of springback; instead, metal formers need to throw out the old rulebooks.
