Event Details

Key Take As

  • Understand the origin and effect of elastic and plastic stress (force) and strain (deformation).
  • Learn about the “banana curve” to visually relate specific properties’ ranges for low-strength,
    HSS and AHSS.
  • See the effect that different mechanical properties have on different forming modes.
  • Understand an extremely important steel property heavily used by successful sheetmetal
    forming companies.
  • Study corrective measures for springback, dimensional variation, heat and friction that
    increase as yield strength increases.
  • Review several case studies that reinforce seminar concepts.
  • Get instructions for a free book detailing how to work with HSS and AHSS.
Stuart Keeler

This seminar examines how the steel affects the different modes of forming. The die cannot respond to proprietary names or trade association specifications – only the mechanical properties of the steel. These properties are explained in detail and then related to what happens in the die. Specific topics include springback, deformation gradients, part dimensional variations, sheared (cut) edge damage, forming limit diagrams, forming speed, heat, thermal notches, friction, coatings, lubrication, and surface defects (yield point elongation and orange peel). Steel types include bake hardenable, dent resistant, high-strength low-alloy (HSLA), and stainless. Included is an introduction to the new advanced high strength steels (AHSS): Sheet thickness ranges from 0.03-in. (0.75 mm) to 0.12-in (3.0 mm).


Peter Ulintz, Patricia Miller

The increased force and pressure required to bend, form and cut higher strength materials creates significant problems for press room equipment and stamping dies. The emergence of new advance high strength steels (AHSS) is changing the metal stampings and their tools are designed and processed.

Recent die-process research has proven the effectiveness of several unique methods that address problems specific to AHSS materials, including: proper selection of press room equipment, die process optimization, product design strategies, tool steel selection, and methods for controlling spring back. These topics are discussed in detail and presented along with case studies during this seminar. A performance-based die engineering strategy is also presented.
