Hemming of Thin Gauge Advanced High-Strength Steel


The Auto/Steel Partnership (A/SP) Hemming of Thin Gauge Advanced High-Strength Steel (AHSS) project achieved a 30 percent weight savings with an with extremely tight breakline radii using thinner gauge AHSS for automotive closure panels.

Stamping Tooling Optimization


The Auto/Steel Partnership Stamping Tooling Optimization team conducts research on the leading edge of materials technology to develop optimum standards for durable tools to form advanced high-strength steel (AHSS) at a high value. In the progressive die video, AHSS coils are punched, trimmed and flange-formed in a production setup to evaluate multiple cutting and forming materials. In the U-Bend video, AHSS coils are trimmed and formed in a single stage die that simulates production. For both, cast and wrought tools are coated with various plasma and other treatments and coatings to determine combinations that provide maximum durability.

The A/SP technology roadmap – updated annually and used for annual project planning – documents the current and future technical challenges for automotive steel applications. The roadmap captures technical areas of interest and need within the industry and is mapped against when the technology is needed for application (end date of the project area) and when the projects supporting the technical area need to begin to achieve the desired results at the appropriate time. In addition, the roadmap indicates which projects are best suited for pre-competitive collaboration within the A/SP and which project areas are better suited for other organizations such as research for universities, design for automakers or steel development.
